加密专用处理器指令集设计

摘要

源码分析技术是一种重要的专用处理器设计方法,用于定位程序运行的瓶颈所在.通过新颖的细粒度源码分析技术,针对加密应用,扩展的开源可扩展处理器OR1K指令集以协处理器的方式和主处理器紧密耦合,可以获得相比传统设计方法更高的效率和更好的性能.实验结果表明,指令扩展后的处理器相比原处理器在增加较少芯片面积消耗的情况下处理效率提高为扩展前的1.78倍.%Source code analysis technology is an important processor design method, which is efficient in fixing the bottleneck of algorithm. The novel fine - grained code analysis technology extends the instruction set of an open source extensible processor OR1K by means of source code profiler, in terms of application of security application, and implements the extended instruction in mode of co -processor with base processor. The experimental result indicates that the extended processor has achieved 1.78 times increased processing efficiency at the cost of small chip area consumed.
