Description
Embedded Characteristics
™
The ARM926EJ-S processor is a member of the ARM9
sors. The ARM926EJ-S implements ARM architecture version 5TEJ and is targeted at multi-
tasking applications where full memory management, high performance, low die size and low
power are all important features.
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. It also supports
8-bit Java instruction set and includes features for efficient execution of Java bytecode, provid-
ing a Java performance similar to a JIT (Just-In-Time compilers), for the next generation of Java-
powered wireless and embedded devices. It includes an enhanced multiplier design for
improved DSP performance.
The ARM926EJ-S processor supports the ARM debug architecture and includes logic to assist
in both hardware and software debug.
The ARM926EJ-S provides a complete high performance processor subsystem, including:
• an ARM9EJ-S
• a Memory Management Unit (MMU)
• separate instruction and data AMBA AHB bus interfaces
• ARM9EJ-S
• Three Instruction Sets
• 5-Stage Pipeline Architecture when Jazelle is not Used
• 6-Stage Pipeline when Jazelle is Used
• ICache and DCache
