一种面向可重构密码处理器的分布式跨域寄存器文件
A distributed cross-domain register file for reconfigurable cryptographic processor
摘要
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%.关键词
