Abstract
This paper describes a hardware structure realization method of Wallace tree compressor used for mantissa product of 32-bit float-point multiplying unit.Mixed with 3-2 and 4-2 compressor, Wallace tree compressor adopts hardware description language to realize the RTL code writing, and makes use of VCS for functional simulation and synopsys DC for logic synthesis and optimization under SMIC0.13 urn processes.The results show that this kind of compressor benefits the increasing of arithmetic speed during compression process of partial product and reducing of hardware realization area to a large extent.关键词
