【摘要】：本文利用Inverse Butterfly/Butterfly多級(jí)動(dòng)態(tài)網(wǎng)絡(luò)的自重構(gòu)特性,提出了一種針對(duì)循環(huán)移位操作的高速可重構(gòu)控制信息生成算法,該算法不僅具有極高的并行性和較小的資源消耗,還首次將循環(huán)移位、雙向循環(huán)移位和以2~i(i=0,1,2…)為位寬的短字循環(huán)移位等10余種不同類型的移位操作統(tǒng)一在一個(gè)算法中.并在此基礎(chǔ)上,設(shè)計(jì)了一種新型可重構(gòu)移位-置換單元.該單元在SMIC 65nm工藝完成了邏輯綜合.實(shí)驗(yàn)結(jié)果表明,當(dāng)該單元只實(shí)現(xiàn)循環(huán)移位時(shí),與以往研究成果相比,頻率提升了6.4%~12%,面積減小了22%~30%;當(dāng)該單元實(shí)現(xiàn)多種移位操作時(shí),頻率下降約8.4%,但能夠支持的移位操作類型是以往研究成果的2倍.
[Abstract]:Based on the self-reconfiguration characteristic of inverse Butterfly / Butterfly multilevel dynamic network, this paper proposes a high speed reconfigurable control information generation algorithm for cyclic shift operations. This algorithm not only has high parallelism and low resource consumption, but also has the following advantages: 1. The cyclic shift, bidirectional cyclic shift and 1 / 2 / 2 / 2 cyclic shift were also used for the first time. More than 10 different types of shift operations, such as short word cyclic shift with bit width, are unified in one algorithm. On this basis, a new reconfigurable shift-permutation unit is designed. The unit has completed logic synthesis in the SMIC 65nm process. The experimental results show that when the unit only realizes cyclic shift, compared with previous research results, the frequency of the unit is increased by 6.4%, and the area of the unit is reduced by 22 ~ 300.When the unit realizes a variety of shift operations, The frequency decreases by about 8.4%, but the types of shift operations that can be supported are twice as large as those of previous studies.
