PRODUCTION DATA information is current as of publication date. Products conform to specifications per the terms of Texas
Instruments standard warranty. Production processing does not necessarily include testing of all parameters.
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.
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)
ARM Interrupt controller
PLL Controller
Power and Sleep Controller (PSC)
System Module
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
