Abstract :
Instruction set development is an effective way to improve processor performance. In SH-4A core enhancement, Prefix instruction is introduced as a technique to enrich function of original instruction. As a result, we have successfully integrated 130 new 32-bit instructions to 16-bit original instruction set and performance of new core is improved up to 43% compared to conventional model.
