面向序列密码算法的线性运算RISC指令研究
摘要
随着网络信息技术的飞速发展,超大规模集成电路的集成度和工艺水平不断提高,嵌入式处理器逐步登上历史舞台,得到广泛应用。RISC处理器是一个复杂的数字逻辑电路,然而它的基本逻辑部件却并不复杂。RISC以其相比于CISC的独特优势,已经成为嵌入式处理器领域微处理器结构设计的必然选择。但是,RISC在处理一些特殊的功能算法时由于指令简单,实现起来条数较多,执行周期长,存在着严重的效率问题。因此,扩展出专用指令实现特殊功能成为了一种必然的趋势。所以,本课题在基于RISC处理器架构,经过分析多种序列密码算法,结合可重构设计思想,将提取出的密码运算共性逻辑映射为密码功能单元,提出了一种能够高效灵活地实现密码算法的思想——扩展专用指令调用可重构密码功能单元FU实现密码算法。

Abstract
Along with the rapid development of information work, very large scale integrated circuit integrity and technology level increases, embedded processor gradually boarded the stage of history, widely used. RISC processor is plex digital logic circuit, but its basic ponents is plicated. RISC with its unique advantage than CISC, has e embedded processor field microprocessor structure design of the inevitable choice. But, in dealing with some special RISC function algorithm due to simple instructions, and realize the article up several more, execute cycle is long, there are serious efficiency. Therefore, expanded a special instructions realize the special function has e a necessary trend. So, this topic in RISC processor based on structure, through the analysis of many sequence cryptographic algorithm, combining reconfigurable design thought, will the extracted mon logic operations for the password functional unit mapping, and puts forward a kind of highly efficient and flexible to realize the password algorithm of thought-specific instruction calls extended reconfigurable code function units FU realize cryptographic algorithm.
Key Words: Sequence password, reconfigurable, special instructions
