To increase the speed of instructions set simulator(ISS),decode-and-dispatch and optimization methods in simulator's design is studied.Aiming at the problems of a lot of the execution time spent in instruction decode and many local machine instructions executed in instruction execution,the methodology combined decode-and-dispatch with pre-decode is presented to increase ISS's speed.Finally,by design case of a ISS based on SPARC V7 instruction set and analyzing the performance of three kinds of simulators,the validity and efficiency of the presented method is demonstrated.
