Abstract:

Due to the fact that the register files seriously affect the performance and area of coarse-grained reconfigurable cryptographic processors, an efficient structure of the distributed cross-domain register file is proposed to realize a cryptographic processor with a high performance and a low area cost. In order to meet the demands of high performance and high flexibility at a low area cost, a union structure with the multi-ports access structure, i, e., a distributed cross-domain register file, is designed by analyzing the algorithm features of different ciphers. Considering different algorithm requirements of the global register files and local register files, the circuit design is realized by adopting different design parameters under TSMC(Taiwan Semiconductor Manufacturing Company)40 nm CMOS(complementary metal oxide semiconductor)technology and compared with other similar works. The experimental results show that the proposed distributed cross-domain register structure can effectively improve the performance of the unit area, of which the total performance of block per cycle is improved by 17.79% and performance of block per cycle per area is improved by 117%.

由于寄存器文件严重影响可重构密码处理器的性能和面积, 为了实现高性能和低面积消耗的密码处理器, 提出了一种高效的分布式跨域寄存器结构.通过分析不同分组密码的算法特点, 设计了统一的多端口访问结构——分布式跨域寄存器文件.针对全局寄存器文件和局部寄存器文件不同的算法需求, 在TSMC 40 nm CMOS工艺下, 采用不同设计参数分别完成电路实现并与类似结构做比较.实验结果显示, 所提出的分布式跨域寄存器结构能够有效地提升单位面积的性能, 其中单位时间分组密码性能提升了17.79%, 单位面积时间分组密码性能提升了117%.
