基于可重构低功耗处理的高速乘法器设计
A high-speed multiplier based on reconfigurable low-power processing
摘要
Abstract
To address the issues of high latency and high-power consumption associated with tradi-tional radix-4 Booth-encoded multipliers,this paper introduces the implementation of a low-power,high-speed multiplier based on an improved Booth encoding scheme.The multiplier employs an im-proved radix-4 Booth encoding method and utilizes an advance zero encoding module to mitigate power losses caused by conventional encoding.Additionally,a preprocessing approach is adopted to increase extension sign bits,thereby reducing critical path delay.By optimizing the generation rules for the par-tial product array,the number of compressors is reduced.Furthermore,through enhancements to the compressor structure and the adoption of a reconfigurable compression design,the critical path is short-ened,leading to a reduction in overall power consumption of the compression tree.The designed multi-plier is implemented using 180 nm process and synthesized with Design Compiler.For a 32-bit multiplier employing this architecture,the critical path delay is 6.73 ns,the circuit area is 116 736 μm2,and the overall power consumption,obtained through random generation of 5 000 sets of random numbers,is 13 838 μW.关键词
