ARM926EJ-S ARM926EJ-S Jazelle-enhanced macrocell

The ARM926EJ-STM fully synthesizable processor features a Jazelle technology enhanced 32-bit RISC CPU, flexible size instruction and data caches, tightly coupled memory (TCM) interfaces, memory management unit (MMU). It also provides separate instruction and data AMBA AHBTM interfaces particularly suitable for Multi-layer AHB based systems. The ARM926EJ-S processor implements the ARMv5TEJ instruction set and includes an enhanced 16 x 32-bit multiplier, capable of single cycle MAC operations. The ARMv5TEJ instruction set includes 16-bit fixed point DSP instructions to enhance performance of many signal processing algorithms and applications as well as supporting Thumb and Java bytecode execution.

A hardened implementation of the ARM926EJ is now available from the ARM Processor Foundry Program and the DesignStart Program
