摘要
为评估嵌入式处理器性能,提出基于基准测试程序集的嵌入式处理器性能分析方法。基于嵌入式行业广泛使用的飞腾处理器及龙芯处理器,搭建嵌入式处理器基准性能测试平台,分析Dhrystone、Whetstone、Stream、cachebench、CoreMark标准基准测试集的结构和特点,在天脉操作系统平台上移植基准测试用例,对处理器运算性能、存取带宽、核心性能等进行了定量的测试与评估,运用对比策略进行性能分析,为国产嵌入式处理器在航空电子领域的部署和应用提供了一定的依据。
To evaluate the performance of embedded processors,a performance analysis method based on benchmark test program sets is proposed.Based on the Phytium proceseeor and loongson processor widely used in the emdedded industry,the embedded processor benchmark performance test platform was built,the structure and characterristics of the Dhrystone、Whetstone、Stream、Cachebench,and CoreMark standard benchmark sets were analyzed,and the benchmark set were transplanted on the ACoreOS.Quantitative testing and evaluation were conducted on the processor′s computing performance,access bandwidth,core performance,etc.Comparative strategies were used for performance analysis.It provides a certain basis for the deployment and application of domestic embedded processors in the field of avionics.
