This paper present and analyzed four kinds of simulation results: hit rate of data cache, and cost of communications, and affections to the performance due to the long latency of shared data cache, and execution time of applications.

• 本文利用模拟器RSIM对SMPDCA结构进行了详细的性能模拟分析，从数据Cache命中率、通信开销、共享数据Cache的访问延迟对性能的影响以及程序执行时间四个方面给出了模拟结果，并对模拟结果进行了分析。
