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.

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.

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
