高性能64位并行前缀加法器全定制设计
Full - custom design of high - performance 64 - bit Parall - Prefix adder
摘要
Abstract
A parall - prefix adder based on 64 - bit radix - 4 Kogge - Stone tree algorithm principle is proposed in this paper. The architecture is optimized using domino dynamic logic, clock delayed domino and transmission pipes logic, which reduces the gate delay of each stage in the adder dramatically. In order to achieve small layout area and good performance, heuristic Euler algorithm is adopted to determine the block carry generation signals circuit structure, multi - output domino logic is adopted to optimize the block carry propagate signals, and six transmission pipes logic is used to build a half - adder. Using SMIC 0.18 μm 1P4M CMOS process for layout design, the adder's area is 0.137 9mm2. In the worst case, the computation time is 532.26 ps.关键词
