Abstract :
An instruction set architecture scheme (ISA scheme) is proposed for multiple fixed-width instruction sets in embedded RISC processor. The ISA scheme can achieve efficient ISA change in instruction level. Besides, compared to current conditional execution methods, the parallel conditional execution (PCE) supported by ISA scheme has smaller code size and shorter execution cycle.
