摘　　要：An optimization method was presented to be easily applied in retargetable simulator. The substance of this method is to reduce the redundant information of operation code which is caused by the variety of execution frequencies of instructions. By recoding the operation code in the loading part of simulator, times of bit comparison in identification of an instruction will get reduced. Thus the performance of the simulator will be improved. The theoretical analysis and experimental results both prove the validity of this method.An optimization method was presented to be easily applied in retargetable simulator, The substance of this method is to reduce the redundant information of operation code which is caused by the variety of execution frequencies of instructions.
