ARM926EJ-S Processor Overview
9.1
Description
The ARM926EJ-S
™
processor is a member of the ARM9
™
family of general-purpose microprocessors. 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.
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, providing a Java performance similar to a JIT (Just-In-Time com-
pilers), 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.
and software debug.
The ARM926EJ-S provides a complete high performance processor subsystem, including:
• an ARM9EJ-S integer core
• a Memory Management Unit (MMU)
• separate instruction and data AMBA AHB bus interfaces
• separate instruction and data TCM interfaces
