摘要

摘要: 该文构建面向密码应用的多核处理器性能模型，对多核密码处理器设计提供理论支持和有效建议。通过引入密码并行处理特征、数据传输时间、同步时间等因素，建立基于Amdahl定律扩展的多核密码处理器性能模型，基于提出的性能模型，对多核密码处理器设计空间进行搜索。模拟分析表明，影响多核密码处理器性能的关键因素是密码应用的可开发并行度、并行部分所占比例以及运算过程的通信次数。

Abstract: This paper builds a performance model of multicore processor, which applies to the crypto algorithms, and some advisable suggestions and academic supports are given for its design. By introducing parallelism degree, transformation overhead and synchronization time, performance model of multicore crypto processor is built based on the Amdahls law and its extension, and accordingly the design space of multicore crypto processors is searched. Simulation analysis shows that the key factors influencing the performance model of multicore crypto processor are the exploitable parallelism of crypto application, the proportion of parallel part and the communication times in the process of operation.
