摘　　要：对基于阵列乘法器、修正布斯算法 (MBA)乘法器、华莱士 (WT)乘法器和MBA -WT混合乘法器的四种架构的32位乘法器性能进行了比较 ,在选择乘法器时 ,应根据实际应用 ,从面积、速度。Four high speed multiplier architectures are proposed in this paper. They are the array multiplier, the modified Booth multiplier, the Wallace tree multiplier and the MBA WT multiplier. Their performances have been compared with each other. It is the conclusion that area, speed and power should be traded off based on the application, when chosen the multiplier.
