Reconfiguration Mode and its Influence on Performance in Reconfigurable Cipher Processing

重构机制对可重构密码处理系统的性能有着重要的影响,该文从全局、局部、静态、动态几方面提出了流水化可重构密码处理结构中重构机制的分类,给出了各种机制的吞吐率和延迟公式,并分析了几种机制的性能和实现代价,最后给出了在采用局部动态重构机制的可重构密码处理结构中密码处理的性能。

Reconfiguration mode has very important influence on the performance of reconfigurable cipher processing system.In this paper,the classification of reconfiguration mode of pipelined reconfigurable cipher processing architecture is proposed from the aspect of global,local,static and dynamic reconfiguration.The throughput and delay of each mode and their implementation cost are analyzed.The simulation result proved that the local dynamic reconfiguration mode used in an implemented reconfigurable cipher processing system can give good performance and proper hardware cost.
