1.2 Description
The TMS320C64x+™ DSPs (including the TMS320C6457 device) are the highest-performance fixed-point DSP
generation in the TMS320C6000™ DSP platform. The C6457 device is based on the third-generation
high-performance, advanced VelociTI™ very-long-instruction-word (VLIW) architecture developed by Texas
Instruments (TI), making these DSPs an excellent choice for applications including video and telecom
infrastructure, imaging/medical, and wireless infrastructure (WI). The C64x+ devices are upward code-compatible
from previous devices that are part of the C6000™ DSP platform.
Based on 65-nm process technology and with performance of up to 9600 million instructions per second (MIPS) [or
9600 16-bit MMACs per cycle] at a 1.2-GHz clock rate, the C6457 device offers cost-effective solutions to
high-performance DSP programming challenges. The C6457 DSP possesses the operational flexibility of high-speed
controllers and the numerical capability of array processors.
The C64x+ DSP core employs eight functional units, two register files, and two data paths. Like the earlier C6000
devices, two of these eight functional units are multipliers or .M units. Each C64x+ .M unit doubles the multiply
throughput versus the C64x core by performing four 16-bit × 16-bit multiply-accumulates (MACs) every clock
cycle. Thus, eight 16-bit × 16-bit MACs can be executed every cycle on the C64x+ core. At a 1.2-GHz clock rate, this
means 9600 16-bit MMACs can occur every second. Moreover, each multiplier on the C64x+ core can compute one
32-bit × 32-bit MAC or four 8-bit × 8-bit MACs every clock cycle.
The C6457 device includes Serial RapidIO®. This high-bandwidth peripheral dramatically improves system
performance and reduces system cost for applications that include multiple DSPs on a board, such as video and
telecom infrastructures and medical/imaging.

The C6457 DSP integrates a large amount of on-chip memory organized as a two-level memory system. The level-1
(L1) program and data memories on the C6457 device are 32KB each. This memory can be configured as mapped
RAM, cache, or some combination of the two. When configured as cache, L1 program (L1P) is a direct mapped
cache whereas L1 data (L1D) is a two-way set associative cache. The level 2 (L2) memory is shared between program
and data space and is 2048KB in size. L2 memory can also be configured as mapped RAM, cache, or some
combination of the two. L2 is configurable up to 1MB of cache. The C64x+ Megamodule also has a 32-bit peripheral
configuration (CFG) port, an internal DMA (IDMA) controller, a system component with reset/boot control,
interrupt/exception control, a power-down control, and a free-running 32-bit timer for time stamp.
The C6457 device has three high-performance embedded coprocessors [one enhanced Viterbi Decoder Coprocessor
(VCP2) and two enhanced Turbo Decoder Coprocessors (TCP2_A and TCP2_B)] that significantly speed up
channel-decoding operations on-chip. The VCP2 operating at CPU clock ÷ 3 can decode more than 694 7.95-Kbps
adaptive multi-rate (AMR) [K = 9, R = 1/3] voice channels. The VCP2 supports constraint lengths K = 5, 6, 7, 8, and
9, rates R = 3/4, 1/2, 1/3, 1/4, and 1/5, and flexible polynomials, while generating hard decisions or soft decisions.
Each TCP2 operating at CPU clock ÷ 3 can decode up to fifty 384-Kbps or eight 2-Mbps turbo encoded channels
(assuming 6 iterations). The TCP2 implements the max*log-map algorithm and is designed to support all
polynomials and rates required by Third-Generation Partnership Projects (3GPP and 3GPP2), with fully
programmable frame length and turbo interleaver. Decoding parameters such as the number of iterations and
stopping criteria are also programmable. Communications between the VCP2/TCP2s and the CPU are carried out
through the EDMA3 controller.
The C6457 device has a complete set of development tools, which includes: a new C compiler, an assembly optimizer
to simplify programming and scheduling, and a Windows® debugger interface for visibility into source code
execution.

PRODUCT PREVIEW
The C64x+ Central Processing Unit (CPU) consists of eight functional units, two register files, and two data paths
as shown in Figure 2-1. The two general-purpose register files (A and B) each contain 32 32-bit registers for a total
of 64 registers. The general-purpose registers can be used for data or can be data address pointers. The data types
supported include packed 8-bit data, packed 16-bit data, 32-bit data, 40-bit data, and 64-bit data. Values larger than
32 bits, such as 40-bit-long or 64-bit-long values are stored in register pairs, with the 32 LSBs of data placed in an
even register and the remaining 8 or 32 MSBs in the next upper register (which is always an odd-numbered register).
The eight functional units (.M1, .L1, .D1, .S1, .M2, .L2, .D2, and .S2) are each capable of executing one instruction
every clock cycle. The .M functional units perform all multiply operations. The .S and .L units perform a general set
of arithmetic, logical, and branch functions. The .D units primarily load data from memory to the register file and
store results from the register file into memory.
The C64x+ CPU extends the performance of the C64x core through enhancements and new features.
Each C64x+ .M unit can perform one of the following each clock cycle: one 32 × 32 bit multiply, two 16 × 16 bit
multiplies, two 16 × 32 bit multiplies, four 8 × 8 bit multiplies, four 8 × 8 bit multiplies with add operations, and four
16 × 16 multiplies with add/subtract capabilities (including a complex multiply). There is also support for Galois
field multiplication for 8-bit and 32-bit data. Many communications algorithms such as FFTs and modems require
complex multiplication. The complex multiply (CMPY) instruction takes four 16-bit inputs and produces a 32-bit
real and a 32-bit imaginary output. There are also complex multiplies with rounding capability that produces one
32-bit packed output that contain 16-bit real and 16-bit imaginary values. The 32 × 32 bit multiply instructions
provide the extended precision necessary for audio and other high-precision algorithms on a variety of signed and
unsigned 32-bit data types.
The .L or (Arithmetic Logic Unit) now incorporates the ability to do parallel add/subtract operations on a pair of
common inputs. Versions of this instruction exist to work on 32-bit data or on pairs of 16-bit data performing dual
16-bit add and subtracts in parallel. There are also saturated forms of these instructions. The C64x+ core enhances
the .S unit in several ways. In the C64x core, dual 16-bit MIN2 and MAX2 comparisons were only available on the
.L units. On the C64x+ core they are also available on the .S unit which increases the performance of algorithms that
do searching and sorting. Finally, to increase data packing and unpacking throughput, the .S unit allows sustained
high performance for the quad 8-bit/16-bit and dual 16-bit instructions. Unpack instructions prepare 8-bit data for
parallel 16-bit operations. Pack instructions return parallel results to output precision including saturation support.
Other new features include:
• SPLOOP — A small instruction buffer in the CPU that aids in creation of software pipelining loops where
multiple iterations of a loop are executed in parallel. The SPLOOP buffer reduces the code size associated with
software pipelining. Furthermore, loops in the SPLOOP buffer are fully interruptible.
• Compact Instructions — The native instruction size for the C6000 devices is 32 bits. Many common
instructions such as MPY, AND, OR, ADD, and SUB can be expressed as 16 bits if the C64x+ compiler can
restrict the code to use certain registers in the register file. This compression is performed by the code
generation tools.
• Instruction Set Enhancements — As noted above, there are new instructions such as 32-bit multiplications,
complex multiplications, packing, sorting, bit manipulation, and 32-bit Galois field multiplication.

Exception Handling — Intended to aid the programmer in isolating bugs. The C64x+ CPU is able to detect
and respond to exceptions, both from internally detected sources (such as illegal op-codes) and from system
events (such as a watchdog time expiration).
Privilege — Defines user and supervisor modes of operation, allowing the operating system to give a basic level
of protection to sensitive resources. Local memory is divided into multiple pages, each with read, write, and
execute permissions.
Time-Stamp Counter — Primarily targeted for Real-Time Operating System (RTOS) robustness, a
free-running time-stamp counter is implemented in the CPU, which is not sensitive to system stalls.

2.4 Boot Sequence
The boot sequence is a process by which the DSP's internal memory is loaded with program and data sections. The
DSP's internal registers are programmed with predetermined values. The boot sequence is started automatically
after each power-on reset, warm reset, and system reset. A local reset to an individual C64x+ Megamodule should
not affect the state of the hardware boot controller on the device. For more details on the initiators of the resets, see
Section 7.6 ‘‘Reset Controller’’ on page 123.
The C6457 supports several boot processes begins execution at the ROM base address, which contains the
bootloader code necessary to support various device boot modes. The boot processes are software driven; using the
BOOTMODE[3:0] device configuration inputs to determine the software configuration that must be completed.
2.5 Boot Modes Supported
The device supports several boot processes, which leverage the internal boot ROM. Most boot processes are software
driven, using the BOOTMODE[3:0] device configuration inputs to determine the software configuration that must
be completed. From a hardware perspective, there are two possible boot modes:
• Public ROM Boot - C64x+ Megamodule is released from reset and begins executing from the L3 ROM base
address. After performing the boot process (e.g., from I2C ROM, Ethernet, or RapidIO), the C64x+
Megamodule then begins execution from the L2 RAM base address.
• Secure ROM Boot - On secure devices, the C64x+ Megamodule is released from reset and begin executing
from secure ROM. Software in the secure ROM will free up internal RAM pages, after which the C64x+
Megamodule initiates the boot process. The C64x+ Megamodule performs any authentication and decryption
required on the bootloaded image prior to beginning execution.

The boot process performed by the C64x+ Megamodule in public ROM boot and secure ROM boot are determined
by the BOOTMODE[3:0] value in the DEVSTAT register. The C64x+ Megamodule reads this value, and then
executes the associated boot process in software. Table 2-3 shows the supported boot modes.

The C64x+ Megamodule configures the SRIO and an external host loads the application via SRIO
peripheral, using directIO protocol. A doorbell interrupt is used to indicate that the code has been
loaded. For more details on the RapidIO configurations, see Table 2-4.
End of Table 2-3
The C64x+ Megamodule configures Serial RapidIO, EMAC, and EDMA, if required, and brings the code image into
the internal on-chip memory via the protocol defined by the boot method (SRIO EMAC bootloader).

2.9 Development
2.9.1 Development Support
The following products support development of C6000™ DSP-based applications:
• Software Development Tools:
– Code Composer Studio™ Integrated Development Environment (IDE), including Editor C/C++/Assembly
Code Generation, and Debug plus additional development tools
– Scalable, Real-Time Foundation Software (DSP/BIOS™), which provides the basic run-time target software
needed to support any DSP application.
• Hardware Development Tools:
– Extended Development System (XDS™) Emulator (supports C6000™ DSP multiprocessor system debug)
– EVM (Evaluation Module)
2.9.2 Device Support
2.9.2.1 Device and Development-Support Tool Nomenclature
To designate the stages in the product development cycle, TI assigns prefixes to the part numbers of all DSP devices
and support tools. Each DSP commercial family member has one of three prefixes: TMX, TMP, or TMS (e.g.,
TMX320C6457CMH). Texas Instruments recommends two of three possible prefix designators for its support tools:
TMDX and TMDS. These prefixes represent evolutionary stages of product development from engineering
prototypes (TMX/TMDX) through fully qualified production devices/tools (TMS/TMDS).
Device development evolutionary flow:
• TMX: Experimental device that is not necessarily representative of the final device's electrical specifications
• TMP: Final silicon die that conforms to the device's electrical specifications but has not completed quality and
reliability verification
• TMS: Fully qualified production device
Support tool development evolutionary flow:
• TMDX: Development-support product that has not yet completed Texas Instruments internal qualification
testing.
• TMDS: Fully qualified development-support product
TMX and TMP devices and TMDX development-support tools are shipped with the following disclaimer:
"Developmental product is intended for internal evaluation purposes."
TMS devices and TMDS development-support tools have been characterized fully, and the quality and reliability of
the device have been demonstrated fully. TI's standard warranty applies.
Predictions show that prototype devices (TMX or TMP) have a greater failure rate than the standard production
devices. Texas Instruments recommends that these devices not be used in any production system because their
expected end-use failure rate still is undefined. Only qualified production devices are to be used.
TI device nomenclature also includes a suffix with the device family name. This suffix indicates the package type (for
example, CMH), the temperature range (for example, blank is the default case temperature range), and the device
speed range, in megahertz (for example, blank is 1000 MHz [1 GHz]).

3 Device Configuration
On the TMS320C6457 device, certain device configurations like boot mode and endianess, are selected at device
power-on reset. The status of the peripherals (enabled/disabled) is determined after device power-on reset. By
default, the peripherals on the C6457 device are disabled and need to be enabled by software before being used.
3.1 Device Configuration at Device Reset
Note—If a configuration pin must be routed out from the device and it is not driven (Hi-Z state), the
internal pullup/pulldown (IPU/IPD) resistor should not be relied upon. TI recommends the use of an
external pullup/pulldown resistor. For more detailed information on pullup/pulldown resistors and
situations in which external pullup/pulldown resistors are required, see Section 3.6 ‘‘Pullup/Pulldown
Resistors’’ on page 63.

PRODUCT PREVIEW
Table 3-1 describes the C6457 device configuration pins. The logic level is latched at power-on reset to determine
the device configuration. The logic level on the device configuration pins can be set by using external
pullup/pulldown resistors or by using some control device (e.g., FPGA/CPLD) to intelligently drive these pins.
When using a control device, care should be taken to ensure there is no contention on the lines when the device is
out of reset. The device configuration pins are sampled during power-on reset and are driven after the reset is
removed. To avoid contention, the control device must stop driving the device configuration pins of the DSP.

3.2 Peripheral Selection After Device Reset
Several of the peripherals on the TMS320C6457 are controlled by the Power Sleep Controller (PSC). By default, the
SRIO, TCP2_A, TCP2_B, and VCP are held in reset and clock-gated. The memories in these modules are also in a
low-leakage sleep mode. Software is required to turn these memories on. Then, the software enables the modules
(turns on clocks and de-asserts reset) before these modules can be used.
In addition, the EMIFA, HPI, and UTOPIA come up clock-gated and held in reset. Memories in these modules are
already enabled. Software is required to enable these modules before they are used as well.
If one of the above modules is used in the selected ROM boot mode, the ROM code will automatically enable the
module.
PRODUCT PREVIEW
All other modules come up enabled by default and there is no special software sequence to enable. For more detailed
information on the PSC usage, see the TMS320C6457 DSP Power/Sleep Controller PSC User's Guide (literature
number SPRUGL4).

3.6 Pullup/Pulldown Resistors
Proper board design should ensure that input pins to the C6457 device always be at a valid logic level and not
floating. This may be achieved via pullup/pulldown resistors. The C6457 device features internal pullup (IPU) and
internal pulldown (IPD) resistors on most pins to eliminate the need, unless otherwise noted, for external
pullup/pulldown resistors.
For the device configuration pins (listed in Table 3-1), if they are both routed out and are not driven (in Hi-Z state),
it is strongly recommended that an external pullup/pulldown resistor be implemented. Although, internal
pullup/pulldown resistors exist on these pins and they may match the desired configuration value, providing
external connectivity can help ensure that valid logic levels are latched on these device configuration pins. In
addition, applying external pullup/pulldown resistors on the device configuration pins adds convenience to the user
in debugging and flexibility in switching operating modes.
Tips for choosing an external pullup/pulldown resistor:
• Consider the total amount of current that may pass through the pullup or pulldown resistor. Make sure to
include the leakage currents of all the devices connected to the net, as well as any internal pullup or pulldown
resistors.
• Decide a target value for the net. For a pulldown resistor, this should be below the lowest VIL level of all inputs
connected to the net. For a pullup resistor, this should be above the highest VIH level of all inputs on the net.
A reasonable choice would be to target the VOL or VOH levels for the logic family of the limiting device; which,
by definition, have margin to the VIL and VIH levels.
• Select a pullup/pulldown resistor with the largest possible value that can still ensure that the net will reach the
target pulled value when maximum current from all devices on the net is flowing through the resistor. The
current to be considered includes leakage current plus, any other internal and external pullup/pulldown
resistors on the net.
• For bidirectional nets, there is an additional consideration that sets a lower limit on the resistance value of the
external resistor. Verify that the resistance is small enough that the weakest output buffer can drive the net to
the opposite logic level (including margin).
• Remember to include tolerances when selecting the resistor value.
• For pullup resistors, also remember to include tolerances on the DVDD rail.
For most systems:
• A 1-kΩ resistor can be used to oppose the IPU/IPD while meeting the above criteria. Users should confirm this
resistor value is correct for their specific application.
• A 20-kΩ resistor can be used to compliment the IPU/IPD on the device configuration pins while meeting the
above criteria. Users should confirm this resistor value is correct for their specific application.
For more detailed information on input current (II), and the low-level/high-level input voltages (VIL and VIH) for
the TMS320C6457 device, see Section 6.3 ‘‘Electrical Characteristics’’ on page 89.
To determine which pins on the C6457 device include internal pullup/pulldown resistors, see Table 2-6 ‘‘Terminal
Functions’’ on page 33.

PRODUCT PREVIEW
An external pullup/pulldown resistor needs to be used in the following situations:
• Device Configuration Pins: If the pin is both routed out and are not driven (in Hi-Z state), an external
pullup/pulldown resistor must be used, even if the IPU/IPD matches the desired value/state.
• Other Input Pins: If the IPU/IPD does not match the desired value/state, use an external pullup/pulldown
resistor to pull the signal to the opposite rail.

4 System Interconnect
On the TMS320C6457 device, the C64x+ Megamodule, the EDMA3 transfer controllers, and the system peripherals
are interconnected through two switch fabrics. The switch fabrics allow for low-latency, concurrent data transfers
between master peripherals and slave peripherals; for example, through a switch fabric the CPU can send data to the
Viterbi co-processor (VCP2) without affecting a data transfer between the HPI and the DDR2 memory controller.
The switch fabrics also allow for seamless arbitration between the system masters when accessing system slaves.
Two types of buses exist in the C6457 device: data buses and configuration buses. Some C6457 peripherals have both
a data bus and a configuration bus interface, while others only have one type of interface. Furthermore, the bus
interface width and speed varies from peripheral to peripheral. Configuration buses are mainly used to access the
register space of a peripheral and the data buses are used mainly for data transfers. However, in some cases, the
configuration bus is also used to transfer data. For example, data is transferred to the VCP2 and TCP2 via their
configuration bus. Similarly, the data bus can also be used to access the register space of a peripheral. For example,
the EMIFA and DDR2 memory controller registers are accessed through their data bus interface.
The C64x+ Megamodule, the EDMA3 traffic controllers, and the various system peripherals can be classified into
two categories: masters and slaves.
Masters are capable of initiating read and write transfers in the system and do not rely on the EDMA3 for their data
transfers. Slaves on the other hand rely on the EDMA3 to perform transfers to and from them. Examples of masters
include the EDMA3 traffic controllers, SRIO, EMAC, and HPI. Examples of slaves include the McBSP, UTOPIA,
2
and I C.
The C6457 device contains two switch fabrics through which masters and slaves communicate. The data switch
fabric, known as the data switched central resource (SCR), is a high-throughput interconnect mainly used to move
data across the system (for more information, see Section 4.2 ‘‘Data Switch Fabric Connections’’). The data SCR
connects masters to slaves via 128-bit data buses running at a SYSCLK4 frequency (SYSCLK4 is generated from PLL
controller). Peripherals that have a 128-bit data bus interface running at this speed can connect directly to the data
SCR; other peripherals require a bridge.
The configuration switch fabric, also known as the configuration switch central resource (SCR), is mainly used by
the C64x+ Megamodule to access peripheral registers (for more information, see Section 4.3 ‘‘Configuration Switch
Fabric’’). The configuration SCR connects C64x+ Megamodule to slaves via 32-bit configuration buses running at a
SYSCLK4 frequency (SYSCLK4 is generated from PLL controller). As with the data SCR, some peripherals require
the use of a bridge to interface to the configuration SCR. Note that the data SCR also connects to the configuration
SCR.
Bridges perform a variety of functions:
• Conversion between configuration bus and data bus.
• Width conversion between peripheral bus width and SCR bus width.
• Frequency conversion between peripheral bus frequency and SCR bus frequency.
For example, the EMIFA requires a bridge to convert its 64-bit data bus interface into a 128-bit interface so that it
can connect to the data SCR. In the case of the TCP2 and VCP2, a bridge is required to connect the data SCR to the
64-bit configuration bus interface.
Note that some peripherals can be accessed through the data SCR and also through the configuration SCR.

Masters are shown on the left and slaves on the right. The data SCR connects masters to slaves via 128-bit data buses
running at a SYSCLK4 frequency. SYSCLK4 is supplied by the PLL controller and is fixed at a frequency equal to the
CPU frequency divided by 3.
Some peripherals and the C64x+ Megamodule have both slave and master ports. Note that each EDMA3 transfer
controller has an independent connection to the data SCR.
The Serial RapidIO (SRIO) peripheral has two connections to the data SCR. The first connection is used when
descriptors are being fetched from system memory. The other connection is used for all other data transfers.
Not all masters on the C6457 DSP may connect to all slaves. Allowed connections are summarized in Table 4-1.

(SCR). The configuration SCR is mainly used by the C64x+ Megamodule to access peripheral registers. The data
SCR also has a connection to the configuration SCR which allows masters to access most peripheral registers. The
only registers not accessible by the data SCR through the configuration SCR are the device configuration registers
and the PLL controller registers; these can only be accessed by the C64x+ Megamodule.
The configuration SCR uses 32-bit configuration buses running at SYSCLK4 frequency. SYSCLK4 is supplied by the
PLL controller and is fixed at a frequency equal to the CPU frequency divided by 3.

End of Table 4-2
The priority levels should be tuned to obtain the best system performance for a particular application. Lower values
indicate higher priorities. For some masters, the priority values are programmed at the system level by configuring
the PRI_ALLOC register. Details on the PRI_ALLOC register are shown in Table 4-3 and Table 4-4. The C64x+
megamodule, SRIO, and EDMA masters contain registers that control their own priority values.

The priority is enforced when several masters in the system are vying for the same endpoint. Note that the
configuration SCR port on the data SCR is considered a single endpoint meaning priority will be enforced when
multiple masters try to access the configuration SCR. Priority is also enforced on the configuration SCR side when
a master (through the data SCR) tries to access the same endpoint as the C64x+ megamodule.

5.1 Memory Architecture
The TMS320C6457 device contains a 2048KB level-2 memory (L2), a 32KB level-1 program memory (L1P), and a
32KB level-1 data memory (L1D). All memory on the C6457 has a unique location in the memory map (see
Table 2-2 ‘‘TMS320C6457 Memory Map Summary’’ on page 19).
After device reset, L1P and L1D cache are configured as all cache, by default. The L1P and L1D cache can be
reconfigured via software through the L1PMODE field of the L1P Configuration Register (L1PMODE) and the
L1DMODE field of the L1D Configuration Register (L1DCFG) of the C64x+ Megamodule. L1D is a two-way
set-associative cache, while L1P is a direct-mapped cache.
The on-chip bootloader changes the reset configuration for L1P and L1D. For more information, see the
TMS320C6457 Bootloader User's Guide (literature number SPRUGL5).

5.1.4 L3 Memory
The L3 ROM on the device is 64KB. The contents of the ROM are divided into two partitions. The first is the ROM
bootloader with the primary purpose of containing software to boot the device. There is no requirement to block
accesses from this portion to the ROM. The second partition is the secure portion of ROM, which has a secure kernel
that is necessary for support of security features on the device. The secure portion of ROM cannot be accessed both
on secure, and non-secure parts. Only secure supervisors should have access.
Emulation accesses follows the same rules of the secure portion of the ROM. Emulation can access the non-secure
portion of the ROM, but cannot read the secure portion of the ROM.
Memory protection allows an operating system to define who or what is authorized to access L1D, L1P, and L2
memory. To accomplish this, the L1D, L1P, and L2 memories are divided into pages. There are 16 pages of L1P (2KB
each), 16 pages of L1D (2KB each), and 64 pages of L2 (32KB each). The L1D, L1P, and L2 memory controllers in
the C64x+ Megamodule are equipped with a set of registers that specify the permissions for each memory page.
Each page may be assigned with fully orthogonal user and supervisor read, write, and execute permissions. In
addition, a page may be marked as either (or both) locally accessible or globally accessible. A local access is a direct
CPU access to L1D, L1P, and L2, while a global access is initiated by a DMA (either IDMA or the EDMA3) or by
other system masters. Note that EDMA or IDMA transfers programmed by the CPU count as global accesses. On a
secure device, pages can be restricted to secure access only (default) or opened up for public, non-secure access.
The CPU and each of the system masters on the device are all assigned a privilege ID (see Table 5-1). It is only
possible to specify whether memory pages are locally or globally accessible.

Faults are handled by software in an interrupt (or an exception, programmable within the C64x+ megamodule
interrupt controller) service routine. A CPU or DMA access to a page without the proper permissions will:
• Block the access — reads return zero, writes are ignored
• Capture the initiator in a status register — ID, address, and access type are stored
• Signal event to CPU interrupt controller

5.2 Memory Protection
TMS320C6457
Communications Infrastructure Digital Signal Processor
SPRS582B—July 2010
www.ti.com
The software is responsible for taking corrective action to respond to the event and resetting the error status in the
memory controller. For more information on memory protection for L1D, L1P, and L2, see the TMS320C64x+
Megamodule Reference Guide (literature number SPRU871).
5.3 Bandwidth Management
When multiple requestors contend for a single C64x+ Megamodule resource, the conflict is resolved by granting
access to the highest priority requestor. The following four resources are managed by the Bandwidth Management
control hardware:
• Level 1 Program (L1P) SRAM/Cache
• Level 1 Data (L1D) SRAM/Cache
• Level 2 (L2) SRAM/Cache
• Memory-mapped registers configuration bus
PRODUCT PREVIEW
The priority level for operations initiated within the C64x+ Megamodule are declared through registers in the C64x+
Megamodule. These operations are:
• CPU-initiated transfers
• User-programmed cache coherency operations
• IDMA-initiated transfers
The priority level for operations initiated outside the C64x+ Megamodule by system peripherals is declared through
the Priority Allocation Register (PRI_ALLOC), see Section 4.4 ‘‘Bus Priorities’’ on page 69. System peripherals with
no fields in PRI_ALLOC have their own registers to program their priorities.
More information on the bandwidth management features of the C64x+ Megamodule can be found in the
TMS320C64x+ Megamodule Reference Guide (literature number SPRU871.)
5.4 Power-Down Control
The C64x+ Megamodule supports the ability to power-down various parts of the C64x+ Megamodule. The
power-down controller (PDC) of the C64x+ Megamodule can be used to power down L1P, the cache control
hardware, the CPU, and the entire C64x+ Megamodule. These power-down features can be used to design systems
for lower overall system power requirements.
Note—The C6457 does not support power-down modes for the L2 memory at this time.
More information on the power-down features of the C64x+ Megamodule can be found in the TMS320C64x+
Megamodule Reference Guide (literature number SPRU871).

7 C64x+ Peripheral Information and Electrical Specifications
This chapter describes the various peripherals on the TMS320C6457 DSP. Peripheral specific information, timing
diagrams, electrical specifications and register memory maps are described in this chapter.

(A) The data manual provides timing at the device terminal. For output timing analysis, the tester terminal electronics and its transmission line effects must be taken into
account. A transmission line with a delay of 2 ns can be used to produce the desired transmission line effect. The transmission line is intended as a load only. It is not
necessary to add or subtract the transmission line delay (2 ns) from the data sheet timings.
(B) Input requirements in this data sheet are tested with an input slew rate of < 4 Volts per nanosecond (4 V/ns) at the device terminal.
The load capacitance value stated is only for characterization and measurement of AC timing signals. This load
capacitance value does not indicate the maximum load the device is capable of driving.

7.1.3 3.3-V Signal Transition Rates
All timings are tested with an input edge rate of 4 volts per nanosecond (4 V/ns).
7.1.4 Timing Parameters and Board Routing Analysis
The timing parameter values specified in this data sheet do not include delays by board routings. As a good board
design practice, such delays must always be taken into account. Timing values may be adjusted by
increasing/decreasing such delays. TI recommends using the available I/O buffer information specification (IBIS)
models to analyze the timing characteristics correctly. To properly use IBIS models to attain accurate timing analysis
for a given system, see the Using IBIS Models for Timing Analysis application report (literature number SPRA839).
If needed, external logic hardware such as buffers may be used to compensate any timing differences.
For inputs, timing is most impacted by the round-trip propagation delay from the DSP to the external device and
from the external device to the DSP. This round-trip delay tends to negatively impact the input setup time margin,
but also tends to improve the input hold time margins (see Table 7-1 and Figure 7-6).

7.3.1 Power-Supply Sequencing
TI recommends the power-supply sequence shown in Figure 7-7 and described in Table 7-2. The figure shows that
the 1.8-V I/O supply should be ramped first. This is followed by the scaled core supply and the fixed 1.1-V supplies
which must ramp within 5 ms of each other. The 3.3-V I/O supply should ramp up last. Some TI power-supply
devices include features that facilitate power sequencing; for example, Auto-Track or Slow-Start/Enable features.
For more information, visit www.ti.com/dsppower. See the TMS320TCI6468 and TMS329C6457 DSPs Hardware
Design Guide (SPRAAV7) for further details on proper power-supply sequencing.

7.3.2 Power-Supply Decoupling
In order to properly decouple the supply planes from system noise, place as many capacitors (caps) as possible close
to the DSP. These caps need to be close to the DSP, no more than 1.25 cm maximum distance to be effective.
Physically smaller caps are better, such as 0402, but need to be evaluated from a yield/manufacturing point-of-view.
Parasitic inductance limits the effectiveness of the decoupling capacitors, therefore physically smaller capacitors
should be used while maintaining the largest available capacitance value. As with the selection of any component,
verification of capacitor availability over the product's production lifetime should be considered.
7.3.3 Power-Down Operation
One of the power goals for the C6457 is to reduce power dissipation due to unused peripherals. There are different
ways to power down peripherals on the device.
After device reset, all peripherals on the C6457 device are in a disabled state and must be enabled by software before
being used. It is possible to enable only the peripherals needed by the application while keeping the rest disabled.
Note that peripherals in a disabled state are held in reset with their clocks gated. For more information on how to
enable peripherals, see Section 3.2 ‘‘Peripheral Selection After Device Reset’’ on page 60

Peripherals used for booting, like I C and HPI, are automatically enabled after device reset. It is possible to
disable peripherals used for booting after the boot process is complete. This, too, results in gating of the clock(s) to
the powered-down peripheral. Once a peripheral is powered-down, it must remain powered down until the next
device reset.
The C64x+ Megamodule also allows for software-driven power-down management for all of the C64x+
megamodule components through its Power-Down Controller (PDC). The CPU can power-down part or the entire
C64x+ megamodule through the power-down controller based on its own execution thread or in response to an
external stimulus from a host or global controller. More information on the power-down features of the C64x+
Megamodule can be found in the TMS320C64x+ Megamodule Reference Guide (literature number SPRU871).
The primary purpose of the EDMA3 is to service user-programmed data transfers between two memory-mapped
slave endpoints on the device. The EDMA3 services software-driven paging transfers (e.g., data movement between
external memory and internal memory), performs sorting or subframe extraction of various data structures, services
event-driven peripherals such as a McBSP or the UTOPIA port, and offloads data transfers from the device CPU.
The EDMA3 includes the following features:
• Fully orthogonal transfer description
– 3 transfer dimensions:
› Array (multiple bytes)
› Frame (multiple arrays)
› Block (multiple frames)
– Single event can trigger transfer of array, frame, or entire block
– Independent indexes on source and destination
• Flexible transfer definition:
– Increment or FIFO transfer addressing modes
– Linking mechanism allows for ping-pong buffering, circular buffering, and repetitive/continuous
transfers, all with no CPU intervention
– Chaining allows multiple transfers to execute with one event
• 256 PaRAM entries
– Used to define transfer context for channels
– Each PaRAM entry can be used as a DMA entry, QDMA entry, or link entry
• 64 DMA channels
– Manually triggered (CPU writes to channel controller register), external event triggered, and chain
triggered (completion of one transfer triggers another)
• 8 Quick DMA (QDMA) channels
– Used for software-driven transfers
– Triggered upon writing to a single PaRAM set entry
• 6 transfer controllers and 6 event queues with programmable system-level priority
• Interrupt generation for transfer completion and error conditions
• Debug visibility
– Queue watermarking/threshold allows detection of maximum usage of event queues
– Error and status recording to facilitate debug
Each of the transfer controllers has a direct connection to the switched central resource (SCR). Table 4-1 ‘‘SCR
Connection Matrix’’ on page 67 lists the peripherals that can be accessed by the transfer controllers.

7.4 Enhanced Direct Memory Access (EDMA3) Controller
TMS320C6457
Communications Infrastructure Digital Signal Processor
SPRS582B—July 2010
www.ti.com
7.4.1 EDMA3 Device-Specific Information
The EDMA supports two addressing modes: constant addressing and increment addressing mode. Constant
addressing mode is applicable to a very limited set of use cases; for most applications increment mode can be used.
On the C6457 DSP, the EDMA can use constant addressing mode only with the Enhanced Viterbi-Decoder
Coprocessor (VCP2) and the Enhanced Turbo Decoder Coprocessor (TCP2). Constant addressing mode is not
supported by any other peripheral or internal memory in the C6457 DSP. Note that increment mode is supported
by all C6457 peripherals, including VCP2 and TCP2. For more information on these two addressing modes, see the
TMS320C6457 DSP Enhanced DMA (EDMA3) Controller User's Guide (literature number SPRUGK6).
PRODUCT PREVIEW
A DSP interrupt must be generated at the end of an HPI boot operation to begin execution of the loaded application.
Because the DSP interrupt generated by the HPI is mapped to the EDMA event DSP_EVT (DMA channel 0), it will
get recorded in bit 0 of the EDMA Event Register (ER). This event must be cleared by software before triggering
transfers on DMA channel 0. The EDMA3 on the C6457 DSP supports active memory protection, but it does not
support proxied memory protection.
7.4.2 EDMA3 Channel Synchronization Events
The EDMA3 supports up to 64 DMA channels that can be used to service system peripherals and to move data
between system memories. DMA channels can be triggered by synchronization events generated by system
peripherals. Table 7-3 lists the source of the synchronization event associated with each of the DMA channels. On
the C6457, the association of each synchronization event and DMA channel is fixed and cannot be reprogrammed.
For more detailed information on the EDMA3 module and how EDMA3 events are enabled, captured, processed,
prioritized, linked, chained, and cleared, etc., see the TMS320C6457 DSP Enhanced DMA (EDMA3) Controller User's
Guide (literature number SPRUGK6).

1 In addition to the events shown in this table, each of the 64 channels can also be synchronized with the transfer completion or alternate transfer completion events. For more
detailed information on EDMA event-transfer chaining, see the TMS320C6457 DSP Enhanced DMA (EDMA3) Controller User's Guide (literature number SPRUGK6).
2 HPI boot is terminated using a DSP interrupt. The DSP interrupt is registered in bit 0 (channel 0) of the EDMA Event Register (ER). This event must be cleared by software before
triggering transfers on DMA channel 0.

7.5 Interrupts
7.5.1 Interrupt Sources and Interrupt Controller
The CPU interrupts on the C6457 device are configured through the C64x+ Megamodule Interrupt Controller. The
interrupt controller allows for up to 128 system events to be programmed to any of the twelve CPU interrupt inputs
(CPUINT4 - CPUINT15), the CPU exception input (EXCEP), or the advanced emulation logic. The 128 system
events consist of both internally-generated events (within the megamodule) and chip-level events. Table 7-12 shows
the mapping of system events. For more information on the Interrupt Controller, see the TMS320C64x+
Megamodule Reference Guide (literature number SPRU871).

7.6 Reset Controller
The reset controller detects the different type of resets supported on the TMS320C6457 device and manages the
distribution of those resets throughout the device.
Table 7-14 explains further the types of reset, the reset initiator, and the effects of each reset on the device. For more
information on the effects of each reset on the PLL controllers and their clocks, see Section 7.6.7 ‘‘Reset Electrical
Data/Timing’’ on page 128.
Table 7-14
Reset Types
Type
Initiator
Effect(s)
Power-on Reset
POR pin
Resets the entire chip including the test and emulation logic. The device configuration pins are latched
only during POR.
Warm Reset
RESET pin
Resets everything except for the test and emulation logic and PLL2. The emulator stays alive during
warm reset. The device configuration pins are not re-latched. DDR2 memory contents will be preserved
if the user places the DDR2 SDRAM in “Self-Refresh” mode before starting a Warm Reset sequence.
System Reset
Emulator
Serial RapidIO
PLLCTL (1)
System reset, by default, behaves as hard reset, but can be configured as soft reset if initiated by Serial
RapidIO or PLLCTL. Emulator-initiated reset is always a hard reset.
• Hard reset effects are the same as those of a warm reset.
• Soft reset means external memory contents can be maintained, it does not affect the clock logic, or the
power control logic of the peripherals. See 7.6.3 ‘‘System Reset’’ on page 124 for more details.
A system reset does not reset the test and emulation circuitry. The device configuration pins are also not
re-latched.
CPU Local Reset
Watchdog Timer
CPU local reset.
End of Table 7-14
1 All masters in the device have access to the PLLCTL registers.
7.6.1 Power-on Reset (POR Pin)
Power-on reset is initiated by the POR pin and is used to reset the entire device, including the test and emulation
logic. Power-on reset is also referred to as a cold reset because the device usually goes through a power-up cycle.
During power-up, the POR pin must be asserted (driven low) until the power supplies have reached their normal
operating conditions. Note that a device power-up cycle is not required to initiate a power-on reset. For power-on
reset, the main PLL controller comes up in bypass mode and the PLL is not enabled. Other resets do not affect the
state of the PLL or the dividers in the PLL controller. For the secondary PLL, the PLL is enabled and always clocking
when POR is not asserted.
The following sequence must be followed during a power-on reset:
1. Wait for all power supplies to reach normal operating conditions while keeping the POR pin asserted (driven
low). While POR is asserted, all pins except RESETSTAT will be set to high-impedance. After the POR pin is
de-asserted (driven high), all Z group pins, low group pins, and high group pins are set to their reset state and
will remain at their reset state until otherwise configured by their respective peripheral. All peripherals that are
power managed, are disabled after a Power-on Reset and must be enabled through the Device State Control
registers (for more details, see Section 3.2 ‘‘Peripheral Selection After Device Reset’’ on page 60).
2. Clocks are reset, and they are propagated throughout the chip to reset any logic that was using reset
synchronously. All logic is now reset and RESETSTAT will be driven low indicating that the device is in reset.
3. POR must be held active until all supplies on the board are stable then for at least an additional 100 μs + 2000
CLKIN2 cycles.

The C6457 device has several types of resets:
• Power-on reset
• Warm reset
• System reset
• CPU reset
TMS320C6457
Communications Infrastructure Digital Signal Processor
SPRS582B—July 2010

4. The POR pin can now be de-asserted. Reset sampled pin values are latched at this point. PLL2 is taken out of
reset and begins its locking sequence, and all power-on device initialization also begins.
5. After device initialization is complete, the RESETSTAT pin is de-asserted (driven high). By this time, PLL2 has
already completed its locking sequence and is outputting a valid clock. The system clocks of both PLL
controllers are allowed to finish their current cycles and then paused for 10 cycles of their respective system
reference clocks. After the pause, the system clocks are restarted at their default divide by settings.
6. The device is now out of reset and device execution begins as dictated by the selected boot mode.
Note—To most of the device, reset is de-asserted only when the POR and RESET pins are both de-asserted
(driven high). Therefore, in the sequence described above, if the RESET pin is held low past the low period
of the POR pin, most of the device will remain in reset. The RESET pin should not be tied together with the
POR pin.
PRODUCT PREVIEW
7.6.2 Warm Reset (RESET Pin)
A warm reset will reset everything on the device except the PLLs, PLL controller, test, and emulation logic. POR
should also remain de-asserted during this time.
The following sequence must be followed during a warm reset:
1. The RESET pin is pulled active low for a minimum of 24 CLKIN1 cycles. During this time the RESET signal is
able to propagate to all modules (except those specifically mentioned above). All I/O are Hi-Z for modules
affected by RESET, to prevent off-chip contention during the warm reset.
2. Once all logic is reset, RESETSTAT is driven active to denote that the device is in reset.
3. The RESET pin can now be released. A minimal device initialization begins to occur. Note that configuration
pins are not re-latched and clocking is unaffected within the device.
4. After device initialization is complete, the RESETSTAT pin is de-asserted (driven high).
Note—The POR pin should be held inactive (high) throughout the warm reset sequence. Otherwise, if POR
is activated (brought low), the minimum POR pulse width must be met. The RESET pin should not be tied
together with the POR pin.
Note—The DDR2 SDRAM contents will also be preserved if the user places the SDRAM into Self-Refresh
mode before starting a Warm Reset sequence. Please see the TMS320C6457 DSP DDR2 Memory Controller
User’s Guide (literature number SPRUGK5).
7.6.3 System Reset
In a System Reset, test and emulation logic are unaffected. The device configuration pins are also not re-latched.
System reset can be initiated by the emulator or Serial RapidIO or by the PLLCTL:
• Emulator Initiated System Reset: The emulator initiated System Reset is always a Hard Reset. The effects of
a Hard Reset are the same as a Warm Reset (defined in section 7.6.2 ‘‘Warm Reset (RESET Pin)’’ on page 124).
• Serial RapidIO Initiated System Reset: The Serial Rapid IO initiated System Reset can be configured by the
RSTCFG register (section 7.6.6.3 ‘‘Reset Configuration Register’’ on page 127) as a Soft Reset or Hard Reset.
For more information on the Serial RapidIO initiated system reset, see Section 4.2 of the TMS320C6457 DSP
Serial RapidIO (SRIO) User's Guide (literature number SPRUGK4).
• PLLCTL Initiated System Reset: The PLLCTL module can initiate a System Reset using the RSTCTRL
register; see section 7.6.6.2 ‘‘Software Reset Control Register’’ on page 127. The PLLCTL initiated System
Reset can be configured by the RSTCFG register (section 7.6.6.3 ‘‘Reset Configuration Register’’ on page 127)
as a Soft Reset or Hard Reset.

During a soft reset, the following happens:
1. The RESETSTAT pin goes low to indicate an internal reset is being generated. The reset is allowed to propagate
through the system. Internal system clocks are not affected. PLLs also remain locked.
2. After device initialization is complete, the RESETSTAT pin is deasserted (driven high). In addition, the PLL
controllers pause their system clocks for about 10 cycles.
At this point:
› The state of the peripherals before the soft reset is not changed. For example, if McBSP0 was in the
enabled state before soft reset, it will remain in the enabled state after soft reset.
› The I/O pins are controlled as dictated by the DEVSTAT register.
› The DDR2 Memory Controller and EMIFA registers retain their previous values. Only the DDR2
Memory Controller and EMIFA state machines are reset by the soft reset.
› The PLL controllers are operating in the mode prior to soft reset. System clocks are unaffected.
The boot sequence is started after the system clocks are restarted. Since the configuration pins (including the
BOOTMODE[3:0] pins) are not latched with a System Reset, the previous values, as shown in the DEVSTAT
register, are used to select the boot mode.
7.6.4 CPU Reset
Timer1 can provide a local CPU reset if it is set up in watchdog mode.
7.6.5 Reset Priority
If any of the above reset sources occur simultaneously, the PLLCTL processes only the highest priority reset request.
The reset request priorities are as follows (high to low):
• Power-on reset
• Warm reset and system reset
7.6.6 Reset Controller Register
There are three reset controller registers: Reset Type Status (RSTYPE) register (029A 00E4), Software Reset Control
(RSTCTRL) register (029A 00E8), and Reset Configuration (RSTCFG) register (029A 00EC). All three registers fall
in the same memory range as the PLL1 Controller registers [029A 0000 - 029A 0170] (see Table 7-26 ‘‘PLL1
Controller Registers (Including Reset Controller)’’ on page 133).

In the case of a Soft Reset, the clock logic or the power control logic of the peripherals are not affected, and, therefore,
the enabled/disabled state of the peripherals is not affected. The following external memory contents are maintained
during a soft reset:
• DDR2 Memory Controller: The DDR2 Memory Controller registers are not reset. In addition, the DDR2
SDRAM memory content is retained if the user places the DDR2 SDRAM in self-refresh mode before invoking
the soft reset.
• EMIFA: The contents of the memory connected to the EMIFA are retained. The EMIFA registers are not reset.

7.7 PLL1 and PLL1 Controller
This section provides a description of the PLL1 controller. For details on the operation of the PLL controller module,
see the TMS320C6457 DSP Software-Programmable Phase-Locked Loop (PLL) Controller User's Guide (literature
number SPRUGL3).
Note—The PLL1 controller registers can be accessed by any master in the device.
The main PLL is controlled by the standard PLL controller. The PLL controller manages the clock ratios, alignment,
and gating for the system clocks to the device. Figure 7-12 shows a block diagram of the PLL controller. The
following paragraphs define the clocks and PLL controller parameters.

The PLL controller also controls reset propagation through the chip, clock alignment, and test points. The PLL
controller monitors the PLL status and provides an output signal indicating when the PLL is locked.
PLL1 power is supplied externally via the PLL1 power-supply pin (PLLV1). An external EMI filter circuit must be
added to PLLV1, as shown in Figure 7-12. The 1.8-V supply of the EMI filter must be from the same 1.8-V power
plane supplying the I/O power-supply pin, DVDD18. TI requires EMI filter manufacturer Murata, part number
NFM18CC222R1C3 or NFM18CC223R1C3.

All PLL external components (C1, C2, and the EMI Filter) must be placed as close to the C64x+ DSP device as
possible. For the best performance, TI recommends that all the PLL external components be on a single side of the
board without jumpers, switches, or components other than those shown. For reduced PLL jitter, maximize the
spacing between switching signal traces and the PLL external components (C1, C2, and the EMI Filter).
CAUTION—The PLL controller module as described in the TMS320C6457 DSP Software-Programmable
Phase-Locked Loop (PLL) Controller User's Guide (literature number SPRUGL3) includes a superset of
features, some of which are not supported on the TMS320C6457TMS320C6457 DSP. The following sections
describe the registers that are supported; it should be assumed that any registers not included in these
sections is not supported by the C6457 DSP. Furthermore, only the bits within the registers described here
are supported. Avoid writing to any reserved memory location or changing the value of reserved bits.
7.7.1 PLL1 Controller Device-Specific Information
7.7.1.1 Internal Clocks and Maximum Operating Frequencies
The main PLL, used to drive the core, the switch fabric, and a majority of the peripheral clocks (all but the DDR2
clock) requires a PLL controller to manage the various clock divisions, gating, and synchronization. The main PLL
controller has several SYSCLK outputs that are listed below, along with the clock description. Each SYSCLK has a
corresponding divider that divides down the output clock of the PLL. Note that dividers are not programmable
unless explicitly mentioned in the description below.
• SYSREFCLK: Full-rate clock (GEM_CLK1) for C64x+ megamodule.
• SYSCLK2: 1/2-rate clock (GEM_L2_CLK) used to clock the L2 and L2 powerdown controller.
• SYSCLK3: 1/x-rate clock (GEM_TRACE_CLK) for emulation and trace logic of the DSP. The default rate for
this clock is 1/3. This is programmable from /1 to /32, where this clock does not violate the maximum clock
rate of 333 MHz. The data rate on the trace pins are 1/2 of this clock.
• SYSCLK4: 1/3-rate clock (CHIP_CLK3) for the switched central resources (SCRs), EDMA3, VCP2, TCP2_A,
TCP2_B, SRIO, as well as the data bus interfaces of the EMIFA and DDR2 memory controller.
• SYSCLK5: 1/6-rate clock (CHIP_CLK6) for other peripherals (PLL controller, PSC, L3 ROM, McBSPs,
Timer64s, EMAC, HPI, UTOPIA, I2C, and GPIO).
• SYSCLK6: 1/y-rate clock (CHIP_CLKS) for an optional McBSP CLKS module input to drive the clock
generator. The default for this clock is 1/10. This is programmable from /6 to /32, where this clock does not
violate the maximum clock rate of 100 MHz. This clock is also output to the SYSCLKOUT pin.
• SYSCLK7: 1/z-rate clock (EMIF_MCLK) for an optional internal clock for EMIFA. The default for this clock
is 1/10. This is programmable from /6 to /32, where this clock does not violate the maximum clock rate of
166 MHz. The data rate at the pins must not violate 100 MHz.
• SYSCLK8: 1/p-rate clock (SLOW_SYSCLK). The default for this clock is 1/10. This is programmable from /10
to /32.
Note—In case any of the other programmable SYSCLKs are set slower than 1/10 rate, then SYSCLK8
(SLOW_SYSCLK) needs to be programmed to either match, or be slower than, the slowest SYSCLK in the
system.

The minimum CORECLK rise and fall times should also be observed. For the input clock timing requirements, see

Note that there is a minimum and maximum operating frequency for CORECLK(N|P), ALTCORECLK,
SYSREFCLK, SYSCLK3, SYSCLK6, and SYSCLK7. The PLL1 controller must not be configured to exceed any of
these constraints (certain combinations of external core clock input, internal dividers, and PLL multiply ratios might
not be supported). For the PLL clocks input and output frequency ranges, see Table 7-24.

7.7.1.2 PLL1 Controller Operating Modes
The PLL1 controller has two modes of operation: bypass mode and PLL mode. The mode of operation is determined
by the PLLEN bit of the PLL control register (PLLCTL). In PLL mode, SYSREFCLK is generated from the device
input clock CORECLK(N|P) using the divider POSTDIV and the PLL multiplier PLLM. In bypass mode,
CORECLK(N|P) is fed directly to SYSREFCLK.
All hosts (HPI, etc.) must hold off accesses to the DSP while the frequency of its internal clocks is changing. A
mechanism must be in place such that the DSP notifies the host when the PLL configuration has completed.
7.7.1.3 PLL1 Stabilization, Lock, and Reset Times
The PLL stabilization time is the amount of time that must be allotted for the internal PLL regulators to become
stable after device powerup. The PLL should not be operated until this stabilization time has expired.
The PLL reset time is the amount of wait time needed when resetting the PLL (writing PLLRST = 1), in order for the
PLL to properly reset, before bringing the PLL out of reset (writing PLLRST = 0). For the PLL1 reset time value, see
Table 7-25.
The PLL lock time is the amount of time needed from when the PLL is taken out of reset (PLLRST = 1 with
PLLEN = 0) to when to when the PLL controller can be switched to PLL mode (PLLEN = 1). The PLL1 lock time is
given in Table 7-25.

7.8 PLL2
The secondary PLL generates interface clocks for the DDR2 memory controller. Using the DDRCLKSEL pin the user
can select the input source of PLL2 as either the DDRREFCLK or the ALTDDRCLK clock reference sources.
PRODUCT PREVIEW
When coming out of power-on reset, PLL2 is enabled and initialized.
As shown in Figure 7-14, the PLL2 multiplier is fixed at a ×10 multiplier rate followed by a fixed /2 divider resulting
in an effective x5 multiplier going to the DDR2PHY and attached DDR2 memory.

PLL2 power is supplied externally via the PLL2 power supply (PLLV2). An external PLL filter circuit must be added
to PLLV2 as shown in Figure 7-14. The 1.8-V supply for the EMI filter must be from the same 1.8-V power plane
supplying the I/O power-supply pin, DVDD18. TI requires EMI filter manufacturer Murata NFM18CC222R1C3 or
NFM18CC223R1C3. For more information on the external PLL filter or the EMI filter, see the TMS320TCI6484 and
TMS320C6457 DSPs Hardware Design Guide (literature number SPRAAV7).
All PLL external components (capacitors and the EMI filter) should be placed as close to the C64x+ DSP device as
possible. For the best performance, TI requires that all the PLL external components be on a single side of the board
without jumpers, switches, or components other than the ones shown. For reduced PLL jitter, maximize the spacing
between switching signal traces and the PLL external components (capacitors and the EMI filter). The minimum
CLKIN2 rise and fall times should also be observed.
7.8.1 PLL2 Device-Specific Information
7.8.1.1 Internal Clocks and Maximum Operating Frequencies
As shown in Figure 7-14, the output of PLL2, PLLOUT, is divided by 2 and directly fed to the DDR2 memory
controller. This clock is used by the DDR2 memory controller to generate DDR2CLKOUT(N|P)0 and
DDR2CLKOUT(N|P)1. Note that, internally, the data bus interface of the DDR2 memory controller is clocked by
SYSCLK4 and PLL1 controller.

Note that there is a minimum and maximum operating frequency for DDRREFCLK and associated
DDR2CLKOUT(N|P)0 and DDR2CLKOUT(N|P)1. For the PLL clocks input and output frequency ranges, see
Table 7-52.

End of Table 7-52
Unlike the PLL1 which can operate in by-pass and PLL mode, the PLL2 only operates in PLL mode. In PLL mode,
DDR2CLKOUT0(P|N) and DDR2CLKOUT1 (P|N) are generated by an effective x5 multiplier consisting of the
PLL2 fixed x10 multiplier followed by a /2 divider.
The PLL2 is affected by power-on reset. During power-on resets, the internal clocks of the PLL2 are affected as
described in Section 7.6 ‘‘Reset Controller’’ on page 123.

7.9 DDR2 Memory Controller
The 32-bit DDR2 Memory Controller bus of the TMS320C6457 is used to interface to JESD79-2B
standard-compliant DDR2 SDRAM devices. The DDR2 external bus interfaces only to DDR2 SDRAM devices; it
does not share the bus with any other types of peripherals. The decoupling of DDR2 memories from other devices
both simplifies board design and provides I/O concurrency from a second external memory interface, EMIFA.
The internal data bus clock frequency and DDR2 bus clock frequency directly affect the maximum throughput of
the DDR2 bus. The clock frequency of the DDR2 bus is equal to the CLKIN2 frequency multiplied by 10. The
internal data bus clock frequency of the DDR2 Memory Controller is fixed at a divide-by-three ratio of the CPU
frequency. The maximum DDR2 throughput is determined by the smaller of the two bus frequencies. The DDR2
bus is designed to sustain a throughput of up to 2.67 Gbyte/sec at a 667-MHz data rate (333-MHz clock rate) as long
as data requests are pending in the DDR2 Memory Controller.
PRODUCT PREVIEW
7.9.1 DDR2 Memory Controller Device-Specific Information
The approach to specifying interface timing for the DDR2 memory bus is different than on other interfaces such as
EMIF, McBSP, and HPI. For these other interfaces, the device timing was specified in terms of data manual
specifications and I/O buffer information specification (IBIS) models.
For the C6457 DDR2 memory bus, the approach is to specify compatible DDR2 devices and provide the printed
circuit board (PCB) solution and guidelines directly to the user. Texas Instruments (TI) has performed the
simulation and system characterization to ensure all DDR2 interface timings in this solution are met. The complete
DDR2 system solution is documented in the TMS320C6457 DDR2 Implementation Guidelines application report
(literature number SPRAB21).
TI supports only designs that follow the board design guidelines outlined in the application report.
The DDR2 memory controller on the C6457 device supports the following memory topologies:
• A 32-bit wide configuration interfacing to two 16-bit wide DDR2 SDRAM devices.
• A 16-bit wide configuration interfacing to a single 16-bit wide DDR2 SDRAM device.
A race condition may exist when certain masters write data to the DDR2 memory controller. For example, if
master A passes a software message via a buffer in external memory and does not wait for indication that the write
completes, when master B attempts to read the software message, then the master B read may bypass the master A
write and, thus, master B may read stale data and, therefore, receive an incorrect message.
Some master peripherals (e.g., EDMA3 transfer controllers) will always wait for the write to complete before
signaling an interrupt to the system, thus avoiding this race condition. For masters that do not have a hardware
specification of write-read ordering, it may be necessary to specify data ordering via software.
If master A does not wait for indication that a write is complete, it must perform the following workaround:
1. Perform the required write.
2. Perform a dummy write to the DDR2 memory controller module ID and revision register.
3. Perform a dummy read to the DDR2 memory controller module ID and revision register.
4. Indicate to master B that the data is ready to be read after completion of the read in step 3. The completion of
the read in step 3 ensures that the previous write was done.

7.9.3 DDR2 Memory Controller Electrical Data/Timing
The TMS320C6457 DDR2 Implementation Guidelines application report (literature number SPRAB21) specifies a
complete DDR2 interface solution for the C6457 as well as a list of compatible DDR2 devices. TI has performed the
simulation and system characterization to ensure all DDR2 interface timings in this solution are met; therefore, no
electrical data/timing information is supplied here for this interface.
Note—TI supports only designs that follow the board design guidelines outlined in the application report.
7.10 External Memory Interface A (EMIFA)
The EMIFA can interface to a variety of external devices or ASICs, including:
• Pipelined and flow-through synchronous-burst SRAM (SBSRAM)
• ZBT (zero bus turnaround) SRAM and late write SRAM
• Synchronous FIFOs
• Asynchronous memory, including SRAM, ROM, and Flash
For more information about the EMIF peripheral, see the TMS320C6457 DSP External Memory Interface (EMIF)
User's Guide (literature number SPRUGK2).
7.10.1 EMIFA Device-Specific Information
Timing analysis must be done to verify all AC timings are met. TI recommends using I/O buffer information
specification (IBIS) to analyze all AC timings.
To properly use IBIS models to attain accurate timing analysis for a given system, see the Using IBIS Models for
Timing Analysis application report (literature number SPRA839).
To maintain signal integrity, serial termination resistors should be inserted into all EMIF output signal lines (for the
EMIF output signals, see Table 2-6 ‘‘Terminal Functions’’ on page 33).

7.10.3.3 Programmable Synchronous Interface Timing
This section describes the synchronous EMIFA Read and Write timing requirements.
The following parameters are programmable via the EMIFA CE Configuration registers (CEnCFG) (see Table 7-65)
and via the EMIFA Chip Select n Configuration Register (CESECn):
• Read latency (R_LTNCY): 1-, 2-, or 3-cycle read latency
• Write latency (W_LTNCY): 0-, 1-, 2-, or 3-cycle write latency
• ACEx assertion length (CE_EXT): For standard SBSRAM or ZBT SRAM interface, ACEx goes inactive after
the final command has been issued (CE_EXT = 0). For synchronous FIFO interface, ACEx is active when
ASOE is active (CE_EXT = 1).
• Function of ASADS/ASRE (R_ENABLE): For standard SBSRAM or ZBT SRAM interface, ASADS/ASRE
acts as ASADS with deselect cycles (R_ENABLE = 0). For FIFO interface, ASADS/ASRE acts as SRE with NO
deselect cycles (R_ENABLE = 1).
Figure 7-22, Figure 7-23, and Figure 7-24 are given as examples diagrams depicting some of the programmable
options.
• In Figure 7-22, R_LTNCY = 2, CE_EXT = 0, R_ENABLE = 0, and SSEL = 1.
• In Figure 7-23, W_LTNCY = 0, CE_EXT = 0, R_ENABLE = 0, and SSEL = 1.
• In Figure 7-24, W_LTNCY = 1, CE_EXT = 0, R_ENABLE = 0, and SSEL = 1.

2 A Fast-mode I C-bus™ device can be used in a Standard-mode I C-bus™ system, but the requirement tsu(SDA-SCLH) ≥ 250 ns must then be met. This will automatically be the
case if the device does not stretch the LOW period of the SCL signal. If such a device does stretch the LOW period of the SCL signal, it must output the next data bit to the
SDA line tr max + tsu(SDA-SCLH) = 1000 + 250 = 1250 ns (according to the Standard-mode I2C-Bus Specification) before the SCL line is released.
3 A device must internally provide a hold time of at least 300 ns for the SDA signal (referred to the VIHmin of the SCL signal) to bridge the undefined region of the falling edge
of SCL.
4 The maximum th(SDA-SCLL) has only to be met if the device does not stretch the low period [tw(SCLL)] of the SCL signal.
5 Cb = total capacitance of one bus line in pF. If mixed with HS-mode devices, faster fall-times are allowed.

7.12.1 HPI Device-Specific Information
The TMS320C6457 device includes a user-configurable 16-bit or 32-bit Host-port interface (HPI16/HPI32). The
HPIWIDTH pin allows the user configuration of the HPI as a 16-bit or 32-bit peripheral.

End of Table 7-69
Software handshaking via the HRDY bit of the Host Port Control Register (HPIC) is not supported on the C6457.
An HPI boot is terminated using a DSP interrupt. The DSP interrupt is registered in bit 0 (channel 0) of the EDMA
Event Register (ER). This event must be cleared by software before triggering transfers on DMA channel 0.

1 The CPU can write 1 to the HINT bit to generate an interrupt to the host and it can write 1 to the DSPINT bit to clear/acknowledge an interrupt from the host.
2 There are two 32-bit HPIA registers: HPIAR for read operations and HPIAW for write operations. The HPI can be configured such that HPIAR and HPIAW act as a single 32-bit
HPIA (single-HPIA mode) or as two separate 32-bit HPIAs (dual-HPIA mode) from the perspective of the host. The CPU can access HPIAW and HPIAR independently. For
details about the HPIA registers and their modes, see the TMS320C6457 DSP Host Port Interface (HPI) User's Guide (literature number SPRUGK7).

7.13 Multichannel Buffered Serial Port (McBSP)
The McBSP provides these functions:
• Full-duplex communication
• Double-buffered data registers, which allow a continuous data stream
• Independent framing and clocking for receive and transmit
• Direct interface to industry-standard codecs, analog interface chips (AICs), and other serially connected
analog-to-digital (A/D) and digital-to-analog (D/A) devices
• External shift clock or an internal, programmable frequency shift clock for data transfer
For more detailed information on the McBSP peripheral, see the TMS320C6457 DSP Multichannel Buffered Serial
Port (McBSP) Reference Guide (literature number SPRUGK8).
PRODUCT PREVIEW
7.13.1 McBSP Device-Specific Information
The CLKS signal for MCBSP0 and MCBSP1 can be sourced from an external pin or by the PLL1 controller; for
details, see Section 7.7 ‘‘PLL1 and PLL1 Controller’’ on page 130. If the clock from the PLL1 controller is used, the
clock is shared between the two McBSPs.

CLKRP = CLKXP = FSRP = FSXP = 0. If polarity of any of the signals is inverted, then the timing references of that signal are also inverted.
Minimum delay times also represent minimum output hold times.
The CLKS signal is shared by both McBSP0 and McBSP1 on this device.
Minimum CLKR ÷ X cycle times must be met, even when CLKR ÷ X is generated by an internal clock source. Minimum CLKR ÷ X cycle times are based on internal logic speed;
the maximum usable speed may be lower due to EDMA limitations and AC timing requirements
6 P = 1/SYSREFCLK frequency in ns. For example, when running parts at 1000 MHz, use P = 1 ns.
7 Use whichever value is greater
8 Extra delay from FSX high to DX valid applies only to the first data bit of a device, if and only if DXENA = 1 in SPCR.
if DXENA = 0, then D1 = D2 = 0
if DXENA = 1, then D1 = 4P, D2 = 8P

7.14 Ethernet MAC (EMAC)
The Ethernet Media Access Controller (EMAC) module provides an efficient interface between the TMS320C6457
DSP core processor and the networked community. The EMAC supports 10Base-T (10 Mbits/second [Mbps]), and
100BaseTX (100 Mbps), in half- or full-duplex mode, and 1000BaseT (1000 Mbps) in full-duplex mode, with
hardware flow control and quality-of-service (QOS) support.
The EMAC module conforms to the IEEE 802.3-2002 standard, describing the Carrier Sense Multiple Access with
Collision Detection (CSMA/CD) Access Method and Physical Layer specifications. The IEEE 802.3 standard has also
been adopted by ISO/IEC and re-designated as ISO/IEC 8802-3:2000(E).
Deviation from this standard, the EMAC module does not use the Transmit Coding Error signal MTXER. Instead
of driving the error pin when an underflow condition occurs on a transmitted frame, the EMAC will intentionally
generate an incorrect checksum by inverting the frame CRC, so that the transmitted frame will be detected as an
error by the network.

The EMAC control module is the main interface between the device core processor, the MDIO module, and the
EMAC module. The relationship between these three components is shown in Figure 7-42. The EMAC control
module contains the necessary components to allow the EMAC to make efficient use of device memory, plus it
controls device interrupts. The EMAC control module incorporates 8K-bytes of internal RAM to hold EMAC buffer
descriptors.

7.14.3 EMAC Electrical Data/Timing (SGMII)
The TMS320TCI6484 and TMS320C6457 DSPs Hardware Design Guide application report (literature number
SPRAAV7) specifies a complete EMAC and SGMII interface solutions for the C6457 as well as a list of compatible
EMAC and SGMII devices. TI has performed the simulation and system characterization to ensure all EMAC and
SGMII interface timings in this solution are met; therefore, no electrical data/timing information is supplied here
for this interface.
Note—TI supports only designs that follow the board design guidelines outlined in the application report.
The Management Data Input/Output (MDIO) module implements the 802.3 serial management interface to
interrogate and controls up to 32 Ethernet PHY(s) connected to the device, using a shared two-wire bus. Application
software uses the MDIO module to configure the auto-negotiation parameters of each PHY attached to the EMAC,
retrieve the negotiation results, and configure required parameters in the EMAC module for correct operation. The
module is designed to allow almost transparent operation of the MDIO interface, with very little maintenance from
the core processor.
The EMAC control module is the main interface between the device core processor, the MDIO module, and the
EMAC module. The relationship between these three components is shown in Figure 7-42.
For more detailed information on the EMAC/MDIO, see the TMS320C6457 DSP EMAC/MDIO Module Reference
Guide (literature number SPRUGK9).

7.16.1 Timers Device-Specific Information
The TMS320C6457 device has two general-purpose timers, Timer0 and Timer1, each of which can be configured as
a general-purpose timer or as a watchdog timer. When configured as a general-purpose timer, each timer can be
programmed as a 64-bit timer or as two separate 32-bit timers.
Each timer is made up of two 32-bit counters: a high counter and a low counter. The timer pins, TINPLx and
TOUTLx are connected to the low counter. The high counter does not have any external device pins.
As mentioned previously, the timers can operate in watchdog mode. When in watchdog mode, the event output
from Timer1 can optionally reset the CPU. In order for the event to trigger the reset when this operation is desired,
the Timer1 watchdog reset selection register (WDRSTSEL) should be set to 1. The WDRSTSEL register is shown in
Table 7-94 and described in Table 7-95.

7.18 Enhanced Turbo Decoder Coprocessor (TCP2)
7.18.1 TCP2 Device-Specific Information
The C6457 device has two high-performance embedded Turbo-Decoder Coprocessors (TCP2_A and TCP2_B) that
significantly speed up channel-decoding operations on-chip. Each TCP2, operating at CPU clock divided-by-3, can
decode up to fifty 384-Kbps or eight 2-Mbps turbo-encoded channels (assuming 6 iterations). The TCP2
implements the max * log-map algorithm and is designed to support all polynomials and rates required by
Third-Generation Partnership Projects (3GPP and 3GPP2), with fully programmable frame length and turbo
interleaver. Decoding parameters such as the number of iterations and stopping criteria are also programmable.
Communications between the TCP2 and the CPU are carried out through the EDMA3 controller.
Each TCP2 supports:
• Parallel concatenated convolutional turbo decoding using the MAP algorithm
• All turbo code rates greater than or equal to 1/5
• 3GPP and CDMA2000 turbo encoder trellis
• 3GPP and CDMA2000 block sizes in standalone mode
• Larger block sizes in shared processing mode
• Both max log MAP and log MAP decoding
• Sliding windows algorithm with variable reliability and prolog lengths
• The prolog reduction algorithm
• Execution of a minimum and maximum number of iterations
• The SNR stopping criteria algorithm
• The CRC stopping criteria algorithm
For more detailed information on the TCP2, see the TMS320C6457 DSP Turbo-Decoder Coprocessor 2 (TCP2)
Reference Guide (literature number SPRUGK1).

interface. The UTOPIA is more simplistic than the Ethernet MAC, in that the UTOPIA is serviced directly by the
EDMA3 controller. The UTOPIA peripheral contains two, two-cell FIFOs, one for transmit and one for receive, with
which to buffer up data sent/received across the pins. There is a transmit and a receive event to the EDMA3 channel
controller to enable servicing.
For more detailed information on the UTOPIA peripheral, see the TMS320C6457 DSP Universal Test and
Operations PHY Interface for ATM 2 (UTOPIA2) (literature number SPRUGL1).

7.20 Serial RapidIO (SRIO) Port
The SRIO port on the TMS320C6457 device is a high-performance, low pin-count interconnect aimed for
embedded markets. The use of the RapidIO interconnect in a baseband board design can create a homogeneous
interconnect environment, providing even more connectivity and control among the components. RapidIO is based
on the memory and device addressing concepts of processor buses where the transaction processing is managed
completely by hardware. This enables the RapidIO interconnect to lower the system cost by providing lower latency,
reduced overhead of packet data processing, and higher system bandwidth, all of which are key for wireless
interfaces. The RapidIO interconnect offers very low pin-count interfaces with scalable system bandwidth based on
10-Gigabit per second (Gbps) bidirectional links.
The PHY part of the RIO consists of the physical layer and includes the input and output buffers (each serial link
consists of a differential pair), the 8-bit/10-bit encoder/decoder, the PLL clock recovery, and the
parallel-to-serial/serial-to-parallel converters.
The C6457 device supports four 1× or one 4× Serial RapidIO links. The RapidIO interface should be designed to
operate at a data rate of 3.125 Gbps per differential pair. This equals 12.5 raw GBaud/s for the 4× RapidIO port, or
approximately 9 Gbps data throughput rate.
7.20.1 Serial RapidIO Device-Specific Information
The approach to specifying interface timing for the SRIO Port is different than on other interfaces such as EMIFA,
HPI, and McBSP. For these other interfaces, the device timing was specified in terms of data manual specifications
and I/O buffer information specification (IBIS) models.

7.22 Emulation Features and Capability
7.22.1 Advanced Event Triggering (AET)
The TMS320C6457 device supports Advanced Event Triggering (AET). This capability can be used to debug
complex problems as well as understand performance characteristics of user applications. AET provides the
following capabilities:
• Hardware Program Breakpoints: specify addresses or address ranges that can generate events such as halting
the processor or triggering the trace capture.
• Data Watchpoints: specify data variable addresses, address ranges, or data values that can generate events
such as halting the processor or triggering the trace capture.
• Counters: count the occurrence of an event or cycles for performance monitoring.
• State Sequencing: allows combinations of hardware program breakpoints and data watchpoints to precisely
generate events for complex sequences.
For more information on AET, see the following documents:
• Using Advanced Event Triggering to Find and Fix Intermittent Real-Time Bugs application report (literature
number SPRA753)
• Using Advanced Event Triggering to Debug Real-Time Problems in High Speed Embedded Microprocessor
Systems application report (literature number SPRA387)

7.22.2 Trace
The C6457 device supports Trace. Trace is a debug technology that provides a detailed, historical account of
application code execution, timing, and data accesses. Trace collects, compresses, and exports debug information
for analysis. Trace works in real-time and does not impact the execution of the system.
For more information on board design guidelines for Trace Advanced Emulation, see the 60-Pin Emulation Header
Technical Reference (literature number SPRU655).

7.22.3 IEEE 1149.1 JTAG
The JTAG interface is used to support boundary scan and emulation of the device. The boundary scan supported
allows for an asynchronous TRST and only the 5 baseline JTAG signals (e.g., no EMU[1:0]) required for boundary
scan. Most interfaces on the device follow the Boundary Scan Test Specification (IEEE1149.1), while all of the SerDes
(SRIO and SGMII) support the AC-coupled net test defined in AC-Coupled Net Test Specification (IEEE1149.6).
It is expected that all compliant devices are connected through the same JTAG interface, in daisy-chain fashion, in
accordance with the specification. The JTAG interface uses 1.8-V LVCMOS buffers, compliant with the Power
Supply Voltage and Interface Standard for Nonterminated Digital Integrated Circuit Specification (EAI/JESD8-5).
7.22.3.1 IEEE 1149.1 JTAG Compatibility Statement
For maximum reliability, the C6457 DSP includes an internal pulldown (IPD) on the TRST pin to ensure that TRST
will always be asserted upon power up and the DSP's internal emulation logic will always be properly initialized
when this pin is not routed out. JTAG controllers from Texas Instruments actively drive TRST high. However, some
third-party JTAG controllers may not drive TRST high but expect the use of an external pullup resistor on TRST.
When using this type of JTAG controller, assert TRST to initialize the DSP after powerup and externally drive TRST
high before attempting any emulation or boundary scan operations.
