It is a big challenge to optimize the instruction sets of System on Chips (SoCs) according to different systems' working environments. The idea of programmable instruction set is an effective method to gain embedded system's re-configurability. This letter presents a logic module for Java processor to be capable of using programmable instruction set. Cost (area, power, and timing) of the module is trivial. Such module is also reusable for other embedded system solutions besides Java systems.展开更多
