1.3 Description

The device is a low-power ARM microprocessor based on an ARM926EJ-S™. The device enables OEMs and ODMs to quickly bring to market devices featuring robust operating

systems support, rich user interfaces, and high processing performance life through the maximum flexibility of a fully integrated mixed processor solution.

The ARM926EJ-S is a 32-bit RISC processor core that performs 32-bit or 16-bit instructions and processes 32-bit, 16-bit, or 8-bit data. The core uses pipelining so that all parts of the processor and memory system can operate continuously.

The ARM core has a coprocessor 15 (CP15), protection module, and Data and program Memory Management Units (MMUs) with table look-aside buffers. It has separate 16K-byte instruction and 16K-byte data caches. Both are four-way associative with virtual index virtual tag (VIVT). The ARM core also has a 8KB RAM (Vector Table) and 64KB ROM.

The peripheral set includes: a 10/100 Mb/s Ethernet MAC (EMAC) with a Management Data Input/Output (MDIO) module; two inter-integrated circuit (I2C) Bus interfaces; 3 multichannel audio serial port (McASP) with 16/12/4 serializers and FIFO buffers; 2 64-bit general-purpose timers each configurable (one configurable as watchdog); a configurable 16-bit host port interface (HPI) ; up to 8 banks of 16 pins of general-purpose input/output (GPIO) with programmable interrupt/event generation modes, multiplexed with other peripherals; 3 UART interfaces (one with RTS and CTS); 3 enhanced high-resolution pulse width modulator (eHRPWM) peripherals; 3 32-bit enhanced capture (eCAP) module peripherals which can be configured as 3 capture inputs or 3 auxiliary pulse width modulator (APWM) outputs; 2 32-bit enhanced quadrature pulse (eQEP) peripherals; and 2 external memory interfaces: an asynchronous and SDRAM external memory interface (EMIFA) for slower memories or peripherals, and a higher speed memory interface (EMIFB) for SDRAM.

www.ti.com

The Ethernet Media Access Controller (EMAC) provides an efficient interface between the device and the network. The EMAC supports both 10Base-T and 100Base-TX, or 10 Mbits/second (Mbps) and 100 Mbps in either half- or full-duplex mode. Additionally an Management Data Input/Output (MDIO) interface is available for PHY configuration.

The HPI, I2C, SPI, USB1.1 and USB2.0 ports allow the device to easily control peripheral devices and/or communicate with host processors.

The rich peripheral set provides the ability to control external peripheral devices and communicate with external processors. For details on each of the peripherals, see the related sections later in this document and the associated peripheral reference guides.

The device has a complete set of development tools for the ARM. These include C compilers and a Windows™ debugger interface for visibility into source code execution.

3.2 Device Compatibility

The ARM926EJ-S RISC CPU is compatible with other ARM9 CPUs from ARM Holdings plc.

3.3 ARM Subsystem

The ARM Subsystem includes the following features:

• ARM926EJ-S RISC processor

• ARMv5TEJ (32/16-bit) instruction set

• Little endian

• System Control Co-Processor 15 (CP15)

• MMU

• 16KB Instruction cache

3.3.1 ARM926EJ-S RISC CPU

The ARM Subsystem integrates the ARM926EJ-S processor. The ARM926EJ-S processor is a member of ARM9 family of general-purpose microprocessors. This processor is targeted at multi-tasking applications where full memory management, high performance, low die size, and low power are all important. The ARM926EJ-S processor supports the 32-bit ARM and 16 bit THUMB instruction sets, enabling the user to trade off between high performance and high code density. Specifically, the ARM926EJ-S processor supports the ARMv5TEJ instruction set, which includes features for efficient execution of Java byte codes, providing Java performance similar to Just in Time (JIT) Java interpreter, but without associated code overhead.

SPRS637B–FEBRUARY 2010–REVISED AUGUST 2010

The ARM926EJ-S processor supports the ARM debug architecture and includes logic to assist in both hardware and software debug. The ARM926EJ-S processor has a Harvard architecture and provides a complete high performance subsystem, including:

• ARM926EJ -S integer core

• CP15 system control coprocessor

• Memory Management Unit (MMU)

• Separate instruction and data caches

• Write buffer

• Separate instruction and data (internal RAM) interfaces

• Separate instruction and data AHB bus interfaces

• Embedded Trace Module and Embedded Trace Buffer (ETM/ETB) For more complete details on the ARM9, refer to the ARM926EJ-S Technical Reference Manual, available

at http://www.arm.com

3.3.2 CP15

The ARM926EJ-S system control coprocessor (CP15) is used to configure and control instruction and data caches, Memory Management Unit (MMU), and other ARM subsystem functions. The CP15 registers are programmed using the MRC and MCR ARM instructions, when the ARM in a privileged mode such as supervisor or system mode.

SPRS637B–FEBRUARY 2010–REVISED AUGUST 2010

3.3.3 MMU

A single set of two level page tables stored in main memory is used to control the address translation, permission checks and memory region attributes for both data and instruction accesses. The MMU uses a single unified Translation Lookaside Buffer (TLB) to cache the information held in the page tables. The MMU features are:

• Standard ARM architecture v4 and v5 MMU mapping sizes, domains and access protection scheme.

• Mapping sizes are: – 1MB (sections) – 64KB (large pages) – 4KB (small pages) – 1KB (tiny pages)

• Access permissions for large pages and small pages can be specified separately for each quarter of the page (subpage permissions)

• Hardware page table walks

• Invalidate entire TLB, using CP15 register 8

• Invalidate TLB entry, selected by MVA, using CP15 register 8

• Lockdown of TLB entries, using CP15 register 10

3.3.4 Caches and Write Buffer

The size of the Instruction cache is 16KB, Data cache is 16KB. Additionally, the caches have the following features:

• Virtual index, virtual tag, and addressed using the Modified Virtual Address (MVA)

• Four-way set associative, with a cache line length of eight words per line (32-bytes per line) and with two dirty bits in the Dcache

• Dcache supports write-through and write-back (or copy back) cache operation, selected by memory region using the C and B bits in the MMU translation tables

• Critical-word first cache refilling

• Cache lockdown registers enable control over which cache ways are used for allocation on a line fill, providing a mechanism for both lockdown, and controlling cache corruption

• Dcache stores the Physical Address TAG (PA TAG) corresponding to each Dcache entry in the TAG RAM for use during the cache line write-backs, in addition to the Virtual Address TAG stored in the TAG RAM. This means that the MMU is not involved in Dcache write-back operations, removing the possibility of TLB misses related to the write-back address.

• Cache maintenance operations provide efficient invalidation of, the entire Dcache or Icache, regions of the Dcache or Icache, and regions of virtual memory.

www.ti.com

The write buffer is used for all writes to a noncachable bufferable region, write-through region and write misses to a write-back region. A separate buffer is incorporated in the Dcache for holding write-back for cache line evictions or cleaning of dirty cache lines. The main write buffer has 16-word data buffer and a four-address buffer. The Dcache write-back has eight data word entries and a single address entry.

3.3.5 Advanced High-Performance Bus (AHB)

The ARM Subsystem uses the AHB port of the ARM926EJ-S to connect the ARM to the Config bus and the external memories. Arbiters are employed to arbitrate access to the separate D-AHB and I-AHB by the Config Bus and the external memories bus.

3.3.6 Embedded Trace Macrocell (ETM) and Embedded Trace Buffer (ETB)

To support real-time trace, the ARM926EJ-S processor provides an interface to enable connection of an Embedded Trace Macrocell (ETM). The ARM926EJ-S Subsystem in the device also includes the Embedded Trace Buffer (ETB). The ETM consists of two parts:

ADVANCEINFORMATION

AM1707

www.ti.com

• Trace Port provides real-time trace capability for the ARM9.

• Triggering facilities provide trigger resources, which include address and data comparators, counter, and sequencers.

The device trace port is not pinned out and is instead only connected to the Embedded Trace Buffer. The ETB has a 4KB buffer memory. ETB enabled debug tools are required to read/interpret the captured trace data.

This device uses ETM9™ version r2p2 and ETB version r0p1. Documentation on the ETM and ETB is available from ARM Ltd. Reference the ' CoreSight™ ETM9™ Technical Reference Manual, revision r0p1' and the 'ETM9 Technical Reference Manual, revision r2p2'.

3.3.7 ARM Memory Mapping

By default the ARM has access to most on and off chip memory areas, EMIFA, EMIFB, and the additional 128K byte on chip SRAM. Likewise almost all of the on chip peripherals are accessible to the ARM by default.

See Table 3-2 for a detailed top level device memory map that includes the ARM memory space.

3.5 Pin Assignments

Extensive use of pin multiplexing is used to accommodate the largest number of peripheral functions in the smallest possible package. Pin multiplexing is controlled using a combination of hardware configuration at device reset and software programmable register settings.

3.5.1 Pin Map (Bottom View)

Figure 3-1 shows the pin assignments for the ZKB package.
