摘　　要：为了提高RSA密码算法在密码芯片上的实现性能,基于SOPC技术设计了一款RSA密码芯片,完成了NIOS II的软硬件协同设计。该硬件系统由处理器、存储模块和自定义指令3部分组成,其关键的模乘模块采用改进的模乘算法和交叉存取设计方案设计实现,显著提高了系统性能。整体设计在ALTERA的CYCLONEII器件上进行了验证与测试,并进行了逻辑综合及布局布线。与传统的RSA密码芯片设计相比,该芯片系统灵活性高,资源占用少。To improve the performance of the hardware implementation of the RSA crypto algorithm, a RSA cryptographic chip based on SOPC is designed, and hardware validation platform is constructed, and then NIOS Ⅱ software design is completed. The hardware is composed of processing unit, storage component and user-defined instruction. The implementation of modular multiplication component ofprocessing unit uses modified modular multiplication algorithm, and improves the plan of interleaved modular multiplication, which conspicuously improves the performance. The whole design is simulated, placed and routed on cyclone Ⅱ device. Compared with the traditional RSA crypto chip, our design is more flexible and has less area.
