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.
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.
