2.2

Device Compatibility

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

The C64x+ DSP core is code-compatible with the C6000™ DSP platform and supports features of the

C64x DSP family.

2.3

ARM Subsystem

The ARM Subsystem is designed to give the ARM926EJ-S (ARM9) master control of the device. In

general, the ARM is responsible for configuration and control of the device; including the DSP Subsystem,

the VPSS Subsystem, and a majority of the peripherals and external memories.

The ARM Subsystem includes the following features:

•

ARM926EJ-S RISC processor

•

ARMv5TEJ (32/16-bit) instruction set

•

Little endian

•

Co-Processor 15 (CP15)

•

MMU

•

16KB Instruction cache

•

8KB Data cache

•

Write Buffer

•

16KB Internal RAM (32-bit-wide access)

•

8KB Internal ROM (ARM bootloader for non-EMIFA boot options)

•

Embedded Trace Module and Embedded Trace Buffer (ETM/ETB)
