摘　　要：为设计灵活高效的安全加密处理器件,提出一种多目标联合定制指令设计方法。该方法通过挖掘加密算法之间的公共频繁计算模式,提高定制指令的适应性。采用该方法对DES、AES、Blowfish、RC4和MD5等主流加密算法进行实验,结果表明其能有效完成定制指令设计,指令集扩展后,5种算法获得了41.9%~63.6%的性能提升。In order to design flexible and efficient security and encryption processing device,this paper proposes a multi-objective joint custom instruction design method.By discovering common frequent computation patterns hidden in encryption algorithms,the flexibility of custom instructions is raised.Custom instructions aiming at five encryption algorithms including DES,AES,Blowfish,RC4 and MD5 are generated by adopting the proposed method.Experimental result shows that the method can fulfill custom instruction design effectively.After instruction set extension,the performance of the five algorithms is improved by 41.9%~63.6% respectively.
