Abstract

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.
