his processor core is based on the ARM926EJ-S processor. The ARM926EJ-S
processor belongs to the ARM9 family of general-purpose microprocessors. The
ARM926EJ-S processor is targeted at multi-tasking applications in which full memory
management, high performance, low die size, and low power are important.
About the
processor
The ARM926EJ-S processor supports the 32-bit ARM and 16-bit Thumb instructions
sets, allowing you to trade off between high performance and high code density.
The processor includes features for efficient execution of Java byte codes,
providing Java performance similar to JIT but without the associated overhead.
The ARM926EJ-S supports the ARM debug architecture, and includes logic to assist in
both hardware and software debug. The processor has a Harvard-cached
architecture and provides a complete high-performance processor subsystem,
including:
ARM926EJ-S integer core
Memory Management Unit (MMU) (see "MemoryManagement Unit (MMU),"
beginning on page 105, for information)
Separate instruction and data AMBA AHB bus interfaces
