10. ARM926EJ-S Processor
10.1 Overview
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
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
™
integer core
 a Memory Management Unit (MMU)
 separate instruction and data AMBA
®
AHB bus interfaces
 separate instruction and data TCM interfaces
