1.1 KeyStone Architecture
TI’s KeyStone Multicore Architecture provides a high-performance structure for integrating RISC and DSP cores
with application-specific coprocessors and I/O. KeyStone is the first of its kind in that it provides adequate internal
bandwidth for nonblocking access to all processing cores, peripherals, coprocessors, and I/O. This is achieved with
four main hardware elements: Multicore Navigator, TeraNet, Multicore Shared Memory Controller, and
HyperLink.
Multicore Navigator is an innovative packet-based manager that controls 8192 queues. When tasks are allocated to
the queues, Multicore Navigator provides hardware-accelerated dispatch that directs tasks to the appropriate
available hardware. The packet-based system on a chip (SoC) uses the 2-Tbps capacity of the TeraNet switched
central resource to move packets. The Multicore Shared Memory Controller enables processing cores to access
shared memory directly without drawing from the TeraNet’s capacity, so packet movement cannot be blocked by
memory access.
HyperLink provides a 50-GBaud chip-level interconnect that allows SoCs to work in tandem. Its low-protocol
overhead and high throughput make Hyperlink an ideal interface for chip-to-chip interconnections. Working with
Multicore Navigator, HyperLink dispatches tasks to tandem devices transparently and executes tasks as if they are
running on local resources.
1.2 Device Description
The TMS320C6670 Communications Infrastructure KeyStone SoC is a member of the C66xx SoC family based on
TI's new KeyStone Multicore SoC Architecture designed specifically for high performance wireless infrastructure
applications. The C6670 provides a very high performance macro basestation platform for developing all wireless
standards including WCDMA/HSPA/HSPA+, TD-SCDMA, GSM, TDD-LTE, FDD-LTE, and WiMAX. Even with
aggregate data rates for 20-MHz LTE systems above 400 Mbps per sector, the C6670 can support two sectors running
at full rate. The C6670 also sets a new standard for clock speed with operating frequencies up to 1.2 GHz.
TI's SoC architecture provides a programmable platform integrating various subsystems (C66x CorePacs, IP
network, radio layers 1 and 2, and transport processing) and uses a queue-based communication system that allows
the SoC resources to operate efficiently and seamlessly. This unique SoC architecture also includes a TeraNet Switch
that enables the wide mix of system elements, from programmable cores to dedicated coprocessors and high speed
IO, to each operate at maximum efficiency with no blocking or stalling.
TI's new C66x core launches a new era of DSP technology by combining fixed-point and floating-point
computational capability in the processor without sacrificing speed, size, or power consumption. The
raw computational performance is an industry-leading 32 GMACS/core and 16 Gflops/core (@ 1.2 GHz operating
frequency). The C66x is also 100% backward compatible with software for C64x+ devices. The C66x core
incorporates 90 new instructions targeted for floating-point (FPi) and vector-math-oriented (VPi) processing.
These enhancements yield tremendous performance improvements in multi-antenna 4.8G signal processing for
algorithms like MIMO and beamforming.
The C6670 contains many wireless basestation coprocessors to offload the bulk of the processing demands of layer 1
and layer 2 base station processing. This keeps the cores free for receiver algorithms and other differentiating
functions. The SoC contains multiple copies of key coprocessors such as the FFTC and TCP3d. A key coprocessor
for enabling high data rates is the bit rate coprocessor (BCP), which handles the entire downlink bit processing chain
and much of the receive bit processing.The architectural elements of the SoC (Multicore Navigator) ensure that all
the bits are processed without any CPU intervention or overhead, allowing the system to make optimal use of its
resources.

processing does not necessarily include testing of all parameters.
The C66x Central Processing Unit (CPU) extends the performance of the C64x+ and C674x CPUs through
enhancements and new features. Many of the new features target increased performance for vector processing. The
C64x+ and C674x CPUs support 2-way SIMD operations for 16-bit data and 4-way SIMD operations for 8-bit data.
On the C66x CPU, the vector processing capability is improved by extending the width of the SIMD instructions.
C66x CPUs can execute instructions that operate on 128-bit vectors. For example the QMPY32 instruction is able
to perform the element-to-element multiplication between two vectors of four 32-bit data each. The C66x CPU also
supports SIMD for floating-point operations. Improved vector processing capability (each instruction can process
multiple data in parallel) combined with the natural instruction-level parallelism of C6000 architecture (e.g
execution of up to 8 instructions per cycle) results in a very high level of parallelism that can be exploited by DSP
programmers through the use of TI's optimized C/C++ compiler.
The C66x 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 thirty-two 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. Multiplies also support 128-bit data.
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). 128-bit data
values are stored in register quadruplets, with the 32 LSBs of data placed in a register that is a multiple of 4 and the
remaining 96 MSBs in the next 3 upper registers.
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.
Each C66x .M unit can perform one of the following fixed-point operations each clock cycle: four 32 × 32 bit
multiplies, sixteen 16 × 16 bit multiplies, four 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. 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. Each C66x .M unit can perform one 16 × 16 bit complex multiply with or without rounding
capabilities, two 16 × 16 bit complex multiplies with rounding capability, and a 32 × 32 bit complex multiply with
rounding capability. The C66x can also perform two 16 × 16 bit and one 32 × 32 bit complex multiply instructions
that multiply a complex number with a complex conjugate of another number with rounding capability.
Communication signal processing also requires an extensive use of matrix operations. Each C66x .M unit is capable
of multiplying a [1 × 2] complex vector by a [2 × 2] complex matrix per cycle with or without rounding capability.
A version also exists allowing multiplication of the conjugate of a [1 × 2] vector with a [2 × 2] complex matrix.
Each C66x .M unit also includes IEEE floating-point multiplication operations from the C674x CPU. This includes
one single-precision multiply each cycle and one double precision multiply every 4 cycles. There is also a
mixed-precision multiply that allows multiplication of a single-precision value by a double-precision value and an
operation allowing multiplication of two single-precision numbers resulting in a double-precision number. The

C66x CPU improves the performance over the C674x double-precision multiplies by adding a instruction allowing
one double-precision multiply per cycle and also reduces the number of delay slots from ten to four. Each C66x .M
unit can also perform one the following floating-point operations each clock cycle: one, two, or four single-precision
multiplies or a complex single-precision multiply.
The .L and .S units can now support up to 64-bit operands. This allows for new versions of many of the arithmetic,
logical, and data packing instructions to allow for more parallel operations per cycle. Additional instructions were
added yielding performance enhancements of the floating point addition and subtraction instructions, including the
ability to perform one double-precision addition or subtraction per cycle. Conversion to/from integer and
single-precision values can now be done on both .L and .S units on the C66x. Also, by taking advantage of the larger
operands, instructions were also added to double the number of these conversions that can be done. The .L unit also
has additional instructions for logical AND and OR instructions, as well as 90 degree or 270 degree rotation of
complex numbers (up to two per cycle). Instructions have also been added that allow for computing the conjugate
of a complex number.
The MFENCE instruction is a new instruction introduced with the C66x DSP. This instruction creates a CPU stall
until the completion of all the CPU-triggered memory transactions, including:
• Cache line fills
• Writes from L1D to L2 or from the CorePac to MSMC and/or other system endpoints
• Victim write backs
• Block or global coherence operations
• Cache mode changes
• Outstanding XMC prefetch requests
This is useful as a simple mechanism for programs to wait for these requests to reach their endpoint. It also provides
ordering guarantees for writes arriving at a single endpoint via multiple paths, multiprocessor algorithms that
depend on ordering, and manual coherence operations.

2.3 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. A hard reset, soft reset or local reset to an individual C66x CorePac should not affect the
state of the hardware boot controller on the device. For more details on the initiators of the resets, see section
7.4 ‘‘Reset Controller’’ on page 122. The bootloader uses a section of the L2 SRAM (start address 0x008F 2DC0 and
end address 0x008F FFFF) during initial booting of the device. For more details on the type of configurations stored
in this reserved L2 section see the Bootloader for the C66x DSP User Guide in ‘‘Related Documentation from Texas
Instruments’’ on page 66.
The C6670 supports several boot processes that 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 and use
the BOOTMODE[12:0] device configuration inputs to determine the software configuration that must be
completed. For more details on boot sequence see the Bootloader for the C66x DSP User Guide in ‘‘Related
Documentation from Texas Instruments’’ on page 66.

2.4 Boot Modes Supported and PLL Settings
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 - C66x CorePac is released from reset and begins executing from the L3 ROM base address.
2
After performing the boot process (e.g., from I C ROM, Ethernet, or RapidIO), the C66x CorePac then begins
execution from the L2 RAM base address.
• Secure ROM Boot - On secure devices, the C66x CorePac is released from reset and begins executing from
secure ROM. Software in the secure ROM will free up internal RAM pages, after which the C66x CorePac
initiates the boot process. The C66x CorePac performs any authentication and decryption required on the
bootloaded image prior to beginning execution.
The boot process performed by the C66x CorePac in public ROM boot and secure ROM boot is determined by the
BOOTMODE[12:0] value in the DEVSTAT register. The C66x CorePac reads this value, and then executes the
associated boot process in software. Figure 2-2 shows the bits associated with BOOTMODE[12:0]. PLL settings are
shown at the end of this section, and the PLL setup details can be found in Section 7.5 ‘‘Main PLL and the PLL
Controller’’ on page 128

2.4.3 PLL Settings
The PLL default settings are determined by the BOOTMODE[12:10] bits. Table 2-13 shows settings for various
input clock frequencies. This will set the PLL to the maximum clock setting for the device.
CLK = CLKIN × (PLLM+1) ÷ (2 × (PLLD+1))
The configuration for the PASS PLL is also shown. The PASS PLL is configured with these values only if the Ethernet
boot mode is selected with the input clock set to match the main PLL clock (not the SGMII SerDes clock). See
Table 2-3 for details on configuring Ethernet boot mode. The output from the PASS PLL goes through an on-chip
divider to reduce the operating frequency before reaching the NETCP. The PASS PLL generates 1050 MHz, and after
the chip divider (/3), applies 350 MHz to the NETCP.
The Main PLL is controlled using a PLL controller and a chip-level MMR. The DDR3 PLL and PASS PLL are
controlled by chip level MMRs. For details on how to set up the PLL see Section 7.5 ‘‘Main PLL and the PLL
Controller’’ on page 128. For details on the operation of the PLL controller module, see the Phase Locked Loop (PLL)
Controller for KeyStone Devices User Guide in 2.9 ‘‘Related Documentation from Texas Instruments’’ on page 66.

2.7 Terminal Functions
The terminal functions table (Table 2-15) identifies the external signal names, the associated pin (ball) numbers, the
pin type (I, O/Z, or I/O/Z), whether the pin has any internal pullup/pulldown resistors, and gives functional pin
descriptions. This table is arranged by function. The power terminal functions table (Table 2-16) lists the various
power supply pins and ground pins and gives functional pin descriptions. Table 2-17 shows all pins arranged by
signal name. Table 2-18 shows all pins arranged by ball number.
There are 17 pins that have a secondary function as well as a primary function. The secondary function is indicated
with a dagger (†).
For more detailed information on device configuration, peripheral selection, multiplexed/shared pins, and
pullup/pulldown resistors, see chapter 3 ‘‘Device Configuration’’ on page 67.
Use the symbol definitions in Table 2-14 when reading Table 2-15.

Definition
Internal 100-μA pulldown or pullup is provided for this terminal. In most systems, a 1-kΩ resistor can
be used to oppose the IPD/IPU. For more detailed information on pulldown/pullup resistors and
situations in which external pulldown/pullup resistors are required, see the Hardware Design Guide for
KeyStone Devices in 2.9 ‘‘Related Documentation from Texas Instruments’’ on page 66.

2.8 Development
2.8.1 Development Support
In case the customer would like to develop their own features and software on the C6670 device, TI offers an
extensive line of development tools for the TMS320C6000™ DSP platform, including tools to evaluate the
performance of the processors, generate code, develop algorithm implementations, and fully integrate and debug
software and hardware modules. The tool's support documentation is electronically available within the Code
Composer Studio™ Integrated Development Environment (IDE).
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)
2.8.2 Device Support
2.8.2.1 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., TMX320CMH). 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.

3 Device Configuration
On the TMS320C6670 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 device are disabled and need to be enabled by software before being used.
3.1 Device Configuration at Device Reset
Table 3-1 describes the 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.
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 3.4 ‘‘Pullup/Pulldown
Resistors’’ on page 85.

3.2 Peripheral Selection After Device Reset
Several of the peripherals on the TMS320C6670 are controlled by the Power Sleep Controller (PSC). By default, the
PCIe, SRIO, HyperLink, RAC, TAC, FFTC, AIF2, TCP3d, TCP3e, 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.
If one of the above modules is used in the selected ROM boot mode, the ROM code will automatically enable the
module.
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 Power Sleep Controller (PSC) for KeyStone Devices User Guide in 2.9 ‘‘Related
Documentation from Texas Instruments’’ on page 66.
3.3 Device State Control Registers
The TMS320C6670 device has a set of registers that are used to control the status of its peripherals. These registers
are shown in Table 3-2.

3.3.4 Kicker Mechanism (KICK0 and KICK1) Register
The Bootcfg module contains a kicker mechanism to prevent any spurious writes from changing any of the Bootcfg
MMR values. When the kicker is locked (which it is initially after power on reset) none of the Bootcfg MMRs are
writable (they are only readable). This mechanism requires two MMR writes to the KICK0 and KICK1 registers with
exact data values before the kicker lock mechanism is un-locked. See Table 3-2 ‘‘Device State Control Registers’’ on
page 68 for the address location. Once released then all the Bootcfg MMRs having write permissions are writable
(the read only MMRs are still read only). The first KICK0 data is 0x83e70b13. The second KICK1 data is 0x95a4f1e0.
Writing any other data value to either of these kick MMRs will lock the kicker mechanism and block any writes to
Bootcfg MMRs. In order to ensure protection to all Bootcfg MMRs, software must always re-lock the kicker
mechanism after completing the MMR writes.
3.3.5 LRESETNMI PIN Status (LRSTNMIPINSTAT) Register
The LRSTNMIPINSTAT Register is used to latch the status of LRESET and NMI based on the setting of

3.3.7 Reset Status (RESET_STAT) Register
The reset status register (RESET_STAT) captures the status of Local reset (LRx) for each of the cores and also the
global device reset (GR). Software can use this information to take different device initialization steps, if desired.
• In case of local reset: The LRx bits are written as 1 and GR bit is written as 0 only when the CorePac receives
an local reset without receiving a global reset.
• In case of global reset: The LRx bits are written as 0 and GR bit is written as 1 only when a global reset is
asserted.
The Reset Status Register is shown in Figure 3-6 and described in Table 3-8.

The BCx bit indicates the boot complete status of the corresponding CorePac. All BCx bits are sticky bits — that is
they can be set only once by the software after device reset and they will be cleared to 0 on all device resets.
Boot ROM code will be implemented such that each CorePac will set its corresponding BCx bit immediately before
branching to the predefined location in memory.
3.3.10 Power State Control (PWRSTATECTL) Register
The PWRSTATECTL register is controlled by the software to indicate the power-saving mode. ROM code reads this
register to differentiate between the various power saving modes. This register is cleared only by POR and will
survive all other device resets. See the Hardware Design Guide for KeyStone Devices in‘‘Related Documentation from
Texas Instruments’’ on page 66 for more information. The Power State Control Register is shown in Figure 3-9 and
described in Table 3-11.

3.3.11 NMI Event Generation to CorePac (NMIGRx) Register
NMIGRx registers are used for generating NMI events to the corresponding CorePac. The C6670 has
four NMIGRx registers (NMIGR0 through NMIGR3). The NMIGR0 register generates an NMI event to CorePac0,
the NMIGR1 register generates an NMI event to CorePac1, and so on. Writing a 1 to the NMIG field generates a
NMI pulse. Writing a 0 has no effect and Reads return 0 and have no other effect. The NMI Event Generation to
CorePac Register is shown in Figure 3-10 and described in Table 3-12.

7.7 PASS PLL
The PASS PLL generates interface clocks for the Network Coprocessor. Using the PACLKSEL pin the user can select
the input source of PASS PLL as either the output of Main PLL mux or the PASSCLK clock reference sources. When
coming out of power-on reset, PASS PLL comes out in a bypass mode and needs to be programmed to a valid
frequency before being enabled and used.

PASS PLL power is supplied via the PASS PLL power-supply pin (AVDDA3). An external EMI filter circuit must be
added to all PLL supplies. Please see the Hardware Design Guide for KeyStone Devices in 2.9 ‘‘Related
Documentation from Texas Instruments’’ on page 66 for detailed recommendations. 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).

7.7.1 PASS PLL Control Registers
The PASS PLL, which is used to drive the Network Coprocessor, does not use a PLL controller. PASS PLL can be
controlled using the PAPLLCTL0 and PAPLLCTL1 registers located in Bootcfg module. These MMRs
(memory-mapped registers) exist inside the Bootcfg space. To write to these registers, software should go through
an un-locking sequence using KICK0/KICK1 registers. For suggested configurable values see 2.4.3 ‘‘PLL Settings’’
on page 35. See 3.3.4 ‘‘Kicker Mechanism (KICK0 and KICK1) Register’’ on page 73 for the address location of the
registers and locking and unlocking sequences for accessing these registers. These registers are reset on POR only.

7.7.2 PASS PLL Device-Specific Information
As shown in Figure 7-25, the output of PASS PLL (PLLOUT) is divided by 3 and directly fed to the Network
Coprocessor. The PASS PLL is affected by power-on reset. During power-on resets, the internal clocks of the PASS
PLL are affected as described in Section 7.4 ‘‘Reset Controller’’ on page 122. The PASS PLL is unlocked only during
the power-up sequence and is locked by the time the RESETSTAT pin goes high. It does not lose lock during any of
the other resets.
7.7.3 PASS PLL Initialization Sequence
The Main PLL and PLL Controller must always be initialized prior to initializing the PASS PLL. The sequence shown
below must be followed to initialize the PASS PLL.
1. In PASSPLLCTL1, write ENSAT = 1 (for optimal PLL operation)
2. In PASSPLLCTL0, write BYPASS = 1 (set the PLL in Bypass)

7.8 Enhanced Direct Memory Access (EDMA3) Controller
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, and offloads data transfers from the device CPU.
There are 3 EDMA channel controllers on the device: EDMA3CC0, EDMA3CC1, and EDMA3CC2.
• EDMA3CC0 has two transfer controllers: EDMA3TC1 andEDMA3TC2.
• EDMA3CC1 has four transfer controllers: EDMA3TC0, EDMA3TC1, EDMA3TC2, and EDMA3TC3.
• EDMA3CC2 has four transfer controllers: EDMA3TC0, EDMA3TC1, EDMA3TC2, and EDMA3TC3.
In the context of this document, EDMA3TCx is associated with EDMA3CCy, and is referred to as EDMA3CCy TCx.
Each of the transfer controllers has a direct connection to the switch fabric. Section 4.2 ‘‘Switch Fabric
Connections Matrix’’ lists the peripherals that can be accessed by the transfer controllers.
EDMA3CC0 is optimized to be used for transfers to/from/within the MSMC and DDR-3 subsytems. The others are
used for the remaining traffic.
Each EDMA3 channel controller 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
• 128 PaRAM entries for EDMA3CC0, 512 each for EDMA3CC1 and EDMA3CC2
– Used to define transfer context for channels
– Each PaRAM entry can be used as a DMA entry, QDMA entry, or link entry
• 16 DMA channels for EDMA3CC0, 64 each for EDMA3CC1 and EDMA3CC2
– 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 per EDMA3CCx
– Used for software-driven transfers
– Triggered upon writing to a single PaRAM set entry
• Two transfer controllers and two event queues with programmable system-level priority for EDMA3CC0, four
transfer controllers and four event queues with programmable system-level priority for each of EDMA3CC1
and EDMA3CC2
• Interrupt generation for transfer completion and error conditions

7.8.1 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 C6670 SoC, the EDMA can use constant addressing mode only with the enhanced Viterbi decoder
coprocessor (VCP) and the enhanced turbo decoder coprocessor (TCP). Constant addressing mode is not supported
by any other peripheral or internal memory in the DSP. Note that increment mode is supported by all peripherals,
including VCP and TCP. For more information on these two addressing modes, see the Enhanced Direct Memory
Access 3 (EDMA3) for KeyStone Devices User Guide in 2.9 ‘‘Related Documentation from Texas Instruments’’ on
page 66.
For the range of memory addresses that include EDMA3 channel controller (EDMA3CC) control registers and
EDMA3 transfer controller (EDMA3TC) control register see Section 2.2 ‘‘Memory Map Summary’’ on page 21.
For memory offsets and other details on EDMA3CC and EDMA3TC Control Registers entries, see the Enhanced
Direct Memory Access 3 (EDMA3) for KeyStone Devices User Guide in 2.9 ‘‘Related Documentation from Texas
Instruments’’ on page 66.

7.8.3 EDMA3 Transfer Controller Configuration
Each transfer controller on the device is designed differently based on considerations like performance
requirements, system topology (like main TeraNet bus width, external memory bus width), etc. The parameters that
determine the transfer controller configurations are:
• FIFOSIZE: Determines the size in bytes for the data FIFO that is the temporary buffer for the in-flight data.
The data FIFO is where the read return data read by the TC read controller from the source endpoint is stored
and subsequently written out to the destination endpoint by the TC write controller.
• BUSWIDTH: The width of the read and write data buses in bytes, for the TC read and write controller,
respectively. This is typically equal to the bus width of the main TeraNet interface.
• Default Burst Size (DBS): The DBS is the maximum number of bytes per read/write command issued by a
transfer controller.
• DSTREGDEPTH: This determines the number of destination FIFO register set. The number of destination
FIFO register set for a transfer controller determines the maximum number of outstanding transfer requests.

7.8.4 EDMA3 Channel Synchronization Events
The EDMA3 supports up to 16 DMA channels for CC0, 64 each for CC1 and CC2 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. The following tables lists the source of the synchronization event associated with
each of the EDMA CC DMA channels. On the C6670, 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 Enhanced Direct Memory Access 3 (EDMA3) for KeyStone
Devices User Guide in 2.9 ‘‘Related Documentation from Texas Instruments’’ on page 66.

7.9 Interrupts
7.9.1 Interrupt Sources and Interrupt Controller
The CPU interrupts on the C6670 device are configured through the C66x CorePac 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 25 internally-generated events (within the CorePac) and 103 chip-level events.
Additional system events are routed to each of the C66x CorePacs to provide chip-level events that are not required
as CPU interrupts/exceptions to be routed to the Interrupt Controller as emulation events. In addition, error-class
events or infrequently used events are also routed through the system event router to offload the C66x CorePac
interrupt selector. This is accomplished through Chip Interrupt Controller (CIC) blocks, CIC[2:0] for C6670 device.
This is clocked using CPU/6.
The event controllers consist of simple combination logic to provide additional events to each C66x CorePac, plus
the EDMA3CC. CIC0 provides 26 additional events (18 that are CorePac-specific plus 8 broadcast) to each of the
C66x CorePacs, CIC1 provides 19 and 21 additional events to CC1 and CC2, respectively, and CIC2 provides 10 and
32 additional events to CC0 and HyperLink, respectively.
The events that are routed to the C66x CorePacs for AET purposes, from those EDMA3CC and FSYNC events that
are not otherwise provided to each C66x CorePac. For more details on the CIC features, please see the Chip Interrupt
Controller (CIC) for KeyStone Devices User Guide in 2.9 ‘‘Related Documentation from Texas Instruments’’ on
page 66.
Note—Modules such as FFTC, TCP3d, TCP3e, TAC, AIF, CP_MPU, BOOT_CFG, and Tracer have level
interrupts and EOI handshaking interface. The EOI value is 0 for TCP3d, TCP3e, TAC, AIF, CP_MPU,
BOOT_CFG, and Tracer. For FFTC, the EOI values are 0 for FFTC_x_INTD0, 1 for FFTC_x_INTD01, 2
for FFTC_x_INTD2, and 3 for FFTC_x_INTD3 (where FFTC_x can be either FFTC_0 or FFTC_1).

7.9.4 NMI and LRESET
The Non-Maskable Interrupts (NMI) can be generated by chip-level registers and the LRESET can be generated by
software writing into LPSC registers. LRESET and NMI can also be asserted by device pins or watchdog timers. One
NMI pin and one LRESET pin are shared by all four CorePacs on the device. The CORESEL[2:0] pins can be
configured to select between the four CorePacs available as shown in Table 7-46.

7.10 Memory Protection Unit (MPU)
The C6670 supports six MPUs:
• One MPU is used to protect main CORE/3 CFG TeraNet (CFG space of all slave devices on the TeraNet is
protected by the MPU).
• Two MPUs are used for packet DMA (one for DATA PORT and another is for CFG PORT).
• One MPU is used for Semaphore.
• One MPU is used for the RAC.
• One MPU is used to protect the main CFG TeraNet of the TE_SCR_3M.
This section contains MPU register map and details of device-specific MPU registers only. For MPU features and
details of generic MPU registers, see the Memory Protection Unit (MPU) for KeyStone Devices User Guide in
2.9 ‘‘Related Documentation from Texas Instruments’’ on page 66.
The following tables show the configuration of each MPU and the memory regions protected by each MPU.

1 The master ID for MSMC is for the transactions initiated by MSMC internally and sent to the DDR.
2 All Traces are set to the same master ID and bit 7 of the master ID needs to be 1.
Note—Some of the PKTDMA based-peripherals require multiple master IDs. Queue Manager Packet DMA
is assigned with 88, 89, 90, 91, but only 88-89 are actually used. For Queue Manager port, 56, 57, 58, 59 are
assigned while only 1 (56) is actually used. For AIF2, 64, 65, 66, 67, 68, 69, 70, 71 are assigned while only 4
(64-67) are actually used. There are two master ID values are assigned for the Queue Manager_second
master port, one master ID for external linking RAM and the other one for the PDSP/MCDM accesses.

7.10.2.1 Programmable Range n Start Address Register (PROGn_MPSAR)
The Programmable Address Start Register holds the start address for the range. This register is writeable by a
supervisor entity only. If NS = 0 (non-secure mode) in the associated MPPA register, then the register is also
writeable only by a secure entity.
The start address must be aligned on a page boundary. The size of the page is 1K byte. The size of the page determines
the width of the address field in MPSAR and MPEAR.

7.10.2.3 Programmable Range n Memory Protection Page Attribute Register (PROGn_MPPA)
The programmable address memory protection page attribute register holds the permissions for the region. This
register is writeable only by a non-debug supervisor entity. If NS = 0 (secure mode) then the register is also writeable
only by a non-debug secure entity. The NS bit is writeable only by a non-debug secure entity. For debug accesses,
the register is writeable only when NS = 1 or EMU = 1.

TMS320C6670 Peripheral Information and Electrical Specifications

TMS320C6670
Multicore Fixed and Floating-Point System-on-Chip
SPRS689D—March 2012
www.ti.com
7.11 DDR3 Memory Controller
The 64-bit DDR3 Memory Controller bus of the TMS320C6670 is used to interface to JEDEC standard-compliant
DDR3 SDRAM devices. The DDR3 external bus interfaces only to DDR3 SDRAM devices; it does not share the bus
with any other types of peripherals.
7.11.1 DDR3 Memory Controller Device-Specific Information
The TMS320C6670 includes one 64-bit wide, 1.5-V DDR3 SDRAM EMIF interface. The DDR3 interface can operate
at 800 mega transfers per second (MTS), 1033 MTS, 1333 MTS, and 1600 MTS.
Due to the complicated nature of the interface, a limited number of topologies will be supported to provide a 16-bit,
32-bit, or 64-bit interface.
The DDR3 electrical requirements are fully specified in the DDR Jedec Specification JESD79-3C. Standard DDR3
SDRAMs are available in 8-bit and 16-bit versions, allowing for the following bank topologies to be supported by
the interface:
• 72-bit: Five 16-bit SDRAMs (including 8 bits of ECC)
• 72-bit: Nine 8-bit SDRAMs (including 8 bits of ECC)
• 36-bit: Three 16-bit SDRAMs (including 4 bits of ECC)
• 36-bit: Five 8-bit SDRAMs (including 4 bits of ECC)
• 64-bit: Four 16-bit SDRAMs
• 64-bit: Eight 8-bit SDRAMs
• 32-bit: Two 16-bit SDRAMs
• 32-bit: Four 8-bit SDRAMs
• 16-bit: One 16-bit SDRAM
• 16-bit: Two 8-bit SDRAMs
The approach to specifying interface timing for the DDR3 memory bus is different than on other interfaces such as
I2C or SPI. 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 DDR3 memory bus, the approach is to specify compatible
DDR3 devices and provide the printed circuit board (PCB) solution and guidelines directly to the user.
A race condition may exist when certain masters write data to the DDR3 memory controller. For example, if
master A passes a software message via a buffer in external memory and does not wait for an indication that the write
completes, before signaling to master B that the message is ready, 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 with TCCMOD=0) 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 to DDR3 memory space.
2. Perform a dummy write to the DDR3 memory controller module ID and revision register.
3. Perform a dummy read to the DDR3 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.

7.11.2 DDR3 Memory Controller Electrical Data/Timing
The DDR3 Implementation Guidelines Application Report in 2.9 ‘‘Related Documentation from Texas
Instruments’’ on page 66 specifies a complete DDR3 interface solution as well as a list of compatible DDR3 devices.
The DDR3 electrical requirements are fully specified in the DDR3 Jedec Specification JESD79-3C. TI has performed
the simulation and system characterization to ensure all DDR3 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.
7.12 I2C Peripheral
The Inter-Integrated Circuit (I2C) module provides an interface between DSP and other devices compliant with
2
2
Philips Semiconductors Inter-IC bus (I C bus) specification version 2.1 and connected by way of an I C bus.
External components attached to this 2-wire serial bus can transmit/receive up to 8-bit data to/from the SoC through
the I2C module.

7.12.1 I C Device-Specific Information
2
2
The TMS320C6670 device includes an I C peripheral module. NOTE: when using the I C module, ensure there are
external pullup resistors on the SDA and SCL pins.
2
The I C modules on the C6670 may be used by the DSP to control local peripheral ICs (DACs, ADCs, etc.) or may
be used to communicate with other controllers in a system or to implement a user interface.
2
The I C port supports:
2
• Compatibility with Philips I C specification revision 2.1 (January 2000)
• Fast mode up to 400 kbps (no fail-safe I/O buffers)
• Noise filter to remove noise of 50 ns or less
• 7-bit and 10-bit device addressing modes
• Multi-master (transmit/receive) and slave (transmit/receive) functionality
• Events: DMA, interrupt, or polling
• Slew-rate limited open-drain output buffers

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 to be met only 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.

7.15 UART Peripheral
The universal asynchronous receiver/transmitter (UART) module provides an interface between the DSP and a
UART terminal interface or other UART-based peripheral. The UART is based on the industry standard TL16C550
asynchronous communications element, which, in turn, is a functional upgrade of the TL16C450. Functionally
similar to the TL16C450 on power up (single character or TL16C450 mode), the UART can be placed in an alternate
FIFO (TL16C550) mode. This relieves the DSP of excessive software overhead by buffering received and transmitted
characters. The receiver and transmitter FIFOs store up to 16 bytes including three additional bits of error status per
byte for the receiver FIFO.
The UART performs serial-to-parallel conversions on data received from a peripheral device and parallel-to-serial
conversion on data received from the DSP. The DSP can read the UART status at any time. The UART includes
control capability and a processor interrupt system that can be tailored to minimize software management of the
communications link. For more information on UART, see the Universal Asynchronous Receiver/Transmitter
(UART) for KeyStone Devices User Guide in 2.9 ‘‘Related Documentation from Texas Instruments’’ on page 66.

7.20 Management Data Input/Output (MDIO)
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 to gigabit Ethernet (GbE) switch
subsystem for correct operation. The module is designed to allow almost transparent operation of the MDIO
interface, with very little attention from the CorePac. For more information, see the Gigabit Ethernet (GbE) Switch
Subsystem for KeyStone Devices User Guide in 2.9 ‘‘Related Documentation from Texas Instruments’’ on page 66.

7.21 Timers
The timers can be used to time events, count events, generate pulses, interrupt the CPU, and send synchronization
events to the EDMA3 channel controller.
7.21.1 Timers Device-Specific Information
The TMS320C6670 device has eight 64-bit timers in total. Of which Timer0 through Timer3 are dedicated to each
of the four CorePacs as a watchdog timer and can also be used as general-purpose timers. Each of other four timers
can also be configured as a general-purpose timer only, with each timer programmed as a 64-bit timer or as two
separate 32-bit timers.
When operating in 64-bit mode, the timer counts either VBUS clock cycles or input (TINPLx) pulses (rising edge)
and generates an output pulse/waveform (TOUTLx) plus an internal event (TINTLx) on a software-programmable
period. When operating in 32-bit mode, the timer is split into two independent 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 timer pins, TINPHx and TOUTHx are connected to the high counter.
When operating in watchdog mode, the timer counts down to 0 and generates an event. It is a requirement that
software writes to the timer before the count expires, after which the count begins again. If the count ever
reaches 0, the timer event output is asserted. Reset initiated by a watchdog timer can be set by programming ‘‘Reset
Type Status Register (RSTYPE)’’ on page 135 and the type of reset initiated can set by programming ‘‘Reset
Configuration Register (RSTCFG)’’ on page 136. For more information, see the 64-bit Timer (Timer 64) for KeyStone
Devices User Guide in 2.9 ‘‘Related Documentation from Texas Instruments’’ on page 66.

7.26 Bit Rate Coprocessor (BCP)
The BCP is a hardware accelerator for wireless infrastructure. It performs most of the uplink and downlink layer 1
bit processing for 3G and 4G wireless standards. It supports LTE, FDD WCDMA, TD-SCDMA, and WiMAX
802.16-2009 standards. It supports various downlink processing blocks like CRC attachment, turbo encoding, rate
matching, code block concatenation, scrambling, and modulation. It supports various uplink processing blocks like
soft slicer, de-scrambler, de-concatenation, rate de-matching and LLR combining. For more information, see the Bit
Coprocessor (BCP) for KeyStone Devices User Guide in 2.9 ‘‘Related Documentation from Texas Instruments’’ on
page 66.
7.27 Serial RapidIO (SRIO) Port
The SRIO port on the device is a high-performance, low pin-count SerDes interconnect. The use of the RapidIO
interconnect in a baseband board design can create a homogeneous interconnect environment, providing
connectivity and control among the components. RapidIO is based on the memory and device addressing concepts
of processor buses in which 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. For more information, see the
Serial RapidIO (SRIO) for KeyStone Devices User Guide in 2.9 ‘‘Related Documentation from Texas Instruments’’

7.29 Semaphore2
The device contains an enhanced Semaphore module for the management of shared resources of the CorePacs. The
Semaphore enforces atomic accesses to shared chip-level resources so that the read-modify-write sequence is not
broken. The Semaphore block has unique interrupts to each of the CorePacs to identify when that CorePac has
acquired the resource.
Semaphore resources within the module are not tied to specific hardware resources. It is a software requirement to
allocate semaphore resources to the hardware resource(s) to be arbitrated.
The Semaphore module supports 3 masters and contains 32 semaphores to be used within the system.
There are two methods of accessing a semaphore resource:
• Direct Access: A CorePac directly accesses a semaphore resource. If free, the semaphore will be granted. If not,
the semaphore is not granted.
• Indirect Access: A CorePac indirectly accesses a semaphore resource by writing it. Once it is free, an interrupt
notifies the CPU that it is available.
7.30 Antenna Interface Subsystem 2 (AIF2)
The enhanced Antenna Interface subsystem (AIF2) consists of the Antenna Interface module and two SerDes
macros. The AIF2 relies on the performance SerDes macro (high-speed serial link) along with a logic layer for the
OBSAI RP3 and CPRI protocols. The AIF is used to connect to the backplane for transmission and reception of
antenna data, as well as to connect to additional device peripherals.
The AIF2 has 11 timer synchronization events from the AIF2 Timer (AT) module. Timer synchronization events
0-7 are routed as primary events to the EDMA3CC1 and also as secondary events to the C66x CorePacs via CIC0.
Timer synchronization events 8, 9, and 10 are hard-wired to TAC, RAC_A, and RAC_B respectively.

7.31 Receive Accelerator Coprocessor (RAC)
The TMS320C6670 has two Receive Accelerator Coprocessor (RAC) subsystems. Each RAC subsystem is a receive
chip-rate accelerator based on a generic correlator coprocessor (GCCP). It supports UMTS (Universal Mobile
Telecommunications System) operations and assists in transferring data received from the antenna to the receive
core and performs receive functions that target the W-CDMA macro bits.
The RAC subsystem consists of several components:
• Two GCCP accelerators for finger despread (FD), path monitor (PM), preamble detection (PD), and stream
power estimator (SPE).
• Back-end interface (BEI) for management of the RAC configuration and the data output.
• Front-end interface (FEI) for reception of the antenna data for processing and access to all MMRs
(memory-mapped registers) and memories in the RAC components.
The RAC has a total of three ports connected to the switch fabric:
• BEI includes two master connections to the switch fabric for output data to device memory. One is 128-bit and
the other is 64-bit, both are clocked at CPU/3 rate.
• The FEI has a 64-bit slave connection to the switch fabric for input data as well as direct memory access (to
facilitate debug).

7.34 Emulation Features and Capability
7.34.1 Advanced Event Triggering (AET)
The 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 the AET, see the following documents in 2.9 ‘‘Related Documentation from Texas
Instruments’’ on page 66:

7.34.2 Trace
The C6670 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.

7.34.3 IEEE 1149.1 JTAG
The JTAG (Joint Test Action Group) interface is used to support boundary scan and emulation of the device. The
boundary scan supported allows for an asynchronous TRST (test reset) 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).

7.34.3.1 IEEE 1149.1 JTAG Compatibility Statement
For maximum reliability, the C6670 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.
