The P1020 is a very flexible device and can be configured to meet many system application needs. Both cores can operate in a symmetric multiprocessing mode to achieve higher performance, or they can run independent operating systems, each performing separate tasks. This flexibility enables application developers to assign distinct processing resources to distinct tasks that need guaranteed performance. For example, one core can manage a data plane and the other a control plane. The value proposition of a dual-core device is further enhanced by a high degree of peripheral integration of system controllers such as DDR controllers. A device with faster internal buses can entirely replace the system controller where a discrete processor without integration was used previously. 1.1 Dual-Core Device Application There are two main ways to map operating systems to the two P1020 cores: • Symmetric multiprocessing • Cooperative asymmetric multiprocessing – Two copies of the same OS that are non-SMP enabled – Two separate operating systems QorIQ™ P1020 Integrated Processor Product Brief, Rev. 0 2 Preliminary—Subject to Change Without Notice Freescale Semiconductor Application Examples Figure 1 shows how to use an integrated dual-core device such as the P1020. A line card uses an ASIC or network processing unit (NPU) for the data path. The ASIC/NPU manages user interfaces on the faceplate on the left as well as the interface to the backplane on the right. The dual-core device is responsible for the control plane. The two cores can operate in an SMP configuration, or two separate operating systems can be used for separate control plane tasks. P1020 Data Plane ASIC/NPU Line Card P1020 P1020 •• • •• • Management Port Services Card Line Card PCI Express Figure 1. Integrated Dual-Core Device Application The lower line card shows the eTSEC interfaces attach to faceplate connectors, and the PCI Express block connects to the backplane switch fabric. The CPUs handle both the control and data plane in a variety of configurations. Two popular alternatives split functionality directionally (one core per direction) or split functionality vertically (one core handling the data plane, one core handling the control plane). At the right of the switch fabric is an example service card, which is easily added to a system to add new features without replacing all the line cards with upgraded ASICs. One service card supports a new feature set in a centralized scheme, receiving traffic from all line cards, so the high performance of a dual-core device is required. The PCI Express port connects to the fabric, and the eTSECs implement a management interface.

All specifications other than those relating to security apply to the non-security version exactly as described in this document. 2.4 Module Features This section contains a high-level view of the P1020 architecture. 2.4.1 e500v2 Cores and Memory Unit The P1020 contains two high-performance 32-bit e500v2 cores that implement the Power Architecture. In addition to 36-bit physical addressing, this version of the e500 core includes the following: • SPE double-precision floating-point instruction set using 64-bit operands • SPE embedded vector and scalar single-precision floating-point instruction set using 32- or 64-bit operands • 32-Kbyte L1 instruction cache and 32-Kbyte L1 data cache with parity protection The device also contains 256 Kbytes of L2 cache/SRAM, as follows: • Four-way set-associative cache organization with 32-byte cache lines • Flexible configuration (can be configured as part cache, part SRAM) • External masters can force data to be allocated into the cache through programmed memory ranges or special transaction types (stashing) • SRAM features include the following: — I/O devices access SRAM regions by marking transactions as snoopable (global) — Regions can reside at any aligned location in the memory map — Byte-accessible ECC uses read-modify-write transaction accesses for smaller-than-cache-line accesses 2.4.2 e500 Coherency Module (ECM) and Address Map The e500 coherency module (ECM) provides a mechanism for I/O-initiated transactions to snoop the bus between the e500v2 cores and the integrated L2 cache in order to maintain coherency across local cacheable memory. It also provides a flexible switch-type structure for core- and I/O-initiated transactions to be routed or dispatched to target modules on the device. The P1020 supports a flexible 36-bit physical address map. Conceptually, the address map consists of local space and external address space. The local address map is supported by ten local access windows that define mapping within the local 36-bit (64-Gbyte) address space. The P1020 can be made part of a larger system address space through the mapping of translation windows. This functionality is included in the address translation and mapping units (ATMUs). Both inbound and outbound translation windows are provided. The ATMUs allows the P1020 to be part of larger address maps such as those of PCI Express.

The USB controller can be configured to operate as a stand-alone host, stand-alone device, or both host and device functions operating simultaneously. The host and device functions are both configured to support the following types of USB transfers: • Bulk QorIQ™ P1020 Integrated Processor Product Brief, Rev. 0 10 Preliminary—Subject to Change Without Notice Freescale Semiconductor Features • • • Control Interrupt Isochronous Some of the key features include the following: • Supports USB dual-role operation and can be configured as host or device • Supports operation as a stand-alone USB device — Supports one upstream facing port — Supports six programmable USB endpoints • Supports operation as a stand-alone USB host controller — Supports USB root hub with one downstream-facing port — Enhanced host controller interface (EHCI) compatible • Supports high-speed (480 Mbps), full-speed (12 Mbps), and low-speed (1.5 Mbps) operations • Supports external PHY with UTMI+ low-pin interface (ULPI) 2.4.6 DDR SDRAM Controller The P1020 supports DDR2 and DDR3 SDRAM. The memory interface controls main memory accesses and provides for a maximum of 4 Gbytes of main memory. The P1020 supports a variety of SDRAM configurations. Sixteen multiplexed address signals provide for device densities from 32 Mbits to 4 Gbits. Four chip select signals support up to four banks of memory. The P1020 supports bank sizes from 32 Mbytes to 4 Gbytes. Five column address strobes (MDM[0:3], MDM8) are used to provide byte selection for memory bank writes. The P1020 can be configured to retain the currently active SDRAM page for pipelined burst accesses. Page mode support of up to 32 simultaneously open pages can dramatically reduce access latencies for page hits. Depending on the memory system design and timing parameters, using page mode can save 3 to 4 clock cycles from subsequent burst accesses that hit in an active page. Using ECC, the P1020 detects and corrects all single-bit errors and detects all double-bit errors and all errors within a nibble. The P1020 can invoke a level of system power management by asserting the MCKE SDRAM signal on-the-fly to put the memory into a low-power sleep mode. The P1020 offers both hardware and software options to support battery-backed main memory. In addition, the DDR controller offers an initialization bypass feature which system designers may use to prevent re-initialization of main memory during system power-on following abnormal shutdown. QorIQ™ P1020 Integrated Processor Product Brief, Rev. 0 Freescale Semiconductor Preliminary—Subject to Change Without Notice 11 Features 2.4.7 High Speed I/O Interfaces The P1020 supports the SGMII and PCI Express high-speed I/O interface standards. 2.4.7.1 PCI Express Interfaces The P1020 supports two PCI Express interfaces designed to comply with the PCI Express Base Specification Revision 1.0a. They are configurable at boot time to act as either root complex or endpoint. The physical layer of the PCI Express interface operates at a transmission rate of 2.5 Gbaud (data rate of 2.0 Gbps) per lane. The theoretical unidirectional peak bandwidth is 2 Gbps per lane. Receive and transmit ports operate independently, resulting in an aggregate theoretical bandwidth of 4 Gbps per lane. Other features of the PCI Express interface include: • Supports two x1 interfaces • Both 32- and 64-bit addressing and 256-byte maximum payload size • Full 64-bit decode with 36-bit wide windows 2.4.7.2 SGMII The serial gigabit media independent interface (SGMII) is a high-speed interface linking the Ethernet controller with an Ethernet PHY. SGMII uses differential signaling for electrical robustness. Only four signals are required: receive data and its inverse, and send data and its inverse; no clock signals are required. 2.4.7.3 High-Speed Interface Multiplexing Table 2 shows the supported high-speed interface configurations. The desired configuration must be selected at power-on reset. Table 2. Supported High-Speed Interface Combinations Lanes 2.4.8 Gbaud A B E F A&B E&F PEX1: x1 PEX2: x1 SGMII2 SGMII3 2.5 1.25 Programmable Interrupt Controller (PIC) The P1020 PIC implements the logic and programming structures of the OpenPIC architecture, providing for external interrupts (with fully nested interrupt delivery), message interrupts, internal-logic driven interrupts, and global high-resolution timers. Up to 16 programmable interrupt priority levels are supported. The PIC can be bypassed to allow use of an external interrupt controller.

The eSDHC acts as a bridge, passing host bus transactions to SD/MMC cards by sending commands and performing data accesses to or from the cards. The eSDHC includes the following features: • SD bus clock frequency up to 50 MHz • Supports 1-/4-bit SD modes, 1-/4-bit MMC modes — Up to 200 Mbps data transfer for SD/MMC cards, using 4 parallel data lines • Supports single- and multi-block read and write • Supports write protection switch for write operations • Supports synchronous and asynchronous abort • Supports pause during the data transfer at a block gap • Supports Auto CMD12 for multi-block transfer • Host can initiate non-data transfer commands while the data transfer is in progress • Embodies a fully configurable 128 × 32-bit FIFO for read/write data • Supports internal DMA capabilities 2.4.11 DMA, I2C, DUART, and Enhanced Local Bus Controller (eLBC) The P1020 provides an integrated four-channel DMA controller, which can transfer data between any of its I/O or memory ports or between two devices or locations on the same port. The DMA controller can be used as follows: • To chain (both extended and direct) through local memory-mapped chain descriptors • To handle misaligned transfers as well as stride transfers and complex transaction chaining QorIQ™ P1020 Integrated Processor Product Brief, Rev. 0 Freescale Semiconductor Preliminary—Subject to Change Without Notice 13 Features • To specify local attributes such as snoop and L2 write stashing There are two I2C controllers. These synchronous, multimaster buses can be connected to additional devices for expansion and system development. The DUART supports full-duplex operation and is compatible with the PC16450 and PC16550 programming models. Both the transmitter and receiver support 16-byte FIFOs. The P1020 enhanced local bus controller (eLBC) port allows connection with a wide variety of external memories, DSPs, and ASICs. Three separate state machines share the same external pins and can be programmed separately to access different types of devices. The general-purpose chip select machine (GPCM) controls accesses to asynchronous devices using a simple handshake protocol. The user programmable machine (UPM) can be programmed to interface with synchronous devices or custom ASIC interfaces. The NAND flash control machine (FCM) further extends interface options. Each chip select can be configured so that the associated chip interface can be controlled by the GPCM, UPM, or FCM controller. All may exist in the same system. The local bus controller supports the following features: • Multiplexed 32-bit address and data bus operating at 100 MHz • Eight chip selects support eight external slaves • Up to eight-beat burst transfers • 16- and 8-bit port sizes controlled by on-chip memory controller • Three protocol engines available on a per-chip-select basis • Parity support • Default boot ROM chip select with configurable bus width (8 or 16 bits) • FCM supports NAND flash, GPCM supports NOR flash 2.4.12 Device Boot Locations The P1020 may be configured to boot using one of the following interfaces: • DDR2/DDR3 memory controller • Any PCI Express interface • Enhanced local bus interface (using the GPCM or FCM) • SPI flash • SD/MMC flash 2.4.13 System Performance Monitor The performance monitor facility supports eight 32-bit counters that can count up to 512 counter-specific events. It supports duration and quantity threshold counting and a burstiness feature that permits counting of burst events with a programmable time between bursts.
