新型可重构移位-置换单元研究与设计
A Novel Reconfigurable Rotation-Permutation Unit Research and Implementation
摘要
Abstract
In this paper,a high speed reconfigurable control bits generation algorithm for rotation shift operations is proposed.The algorithm utilizes self-reconfigurable characteristics of the Inverse Butterfly/Butterfly network,and it is highly parallelized and low-cost.Moreover,it also integrates more than 10 kinds of rotation shift operations together,including rotation shift,bidirectional rotation shift,and sub-word rotation shift based on a bit width of 2i(i=1,2,…).Following this,a new high-speed reconfigurable rotation-permutation unit(HRRU)is developed and synthesized in SMIC 65-nm process.The results show that the proposed unit only containing rotation shift operations,enhances the frequency by 6.4%~12% and reduces the area by 22%~30%,compared with previously proposed solutions.When achieving a variety of rotation shift operations,the frequency of our unit decreases by 8.4%.But it can support twice operations as many as previous designs.关键词
