A design model and microarchitecture implement scheme of simultaneous multithread-ing Godson-2 processor is proposed in this paper. The operating system on simultaneous mul-tithreading Godson-2 processor is designed for operating multiple individual threads simultaneous-ly and improving system level performance. Linux operating system is booted in simultaneous multithreading Godson-2 processor and application programs such as SPEC CPU2000 are executed in it to evaluate performance. It has been shown that simultaneous multithreading Godson-2 pro-cessor improves the performance of superscalar Godson-2 significantly by full exploitation of in-struction-level parallelism. The average speedup is 31.1％.
