In this paper, a new, high-speed multiplication algorithm using tree circuit and a novel inner product generator has been presented. In inner product generation step, a new Smith algorithm has been modified. In inner product reduction step, a new array structure has been proposed. In final addition step, a new algorithm has been used. In this work, improvements in multiplication algorithm by using a faster counter along the tree are presented. In this paper, the novel presented multiplication
more &raquo; ... gorithm has been also analyzed in comparison with other multiplication algorithms. Based on the variation of inner product generator methods, a novel Smith algorithm is proposed. This work, presents a novel approach to reduce power of high-speed multiplication algorithm based on decreasing number of inner products. The reducing elements used into the multiplication algorithm architecture remove some inner product that have not effect in final addition. The proposed array structure and Smith algorithm has major effect in multiplication algorithm performance. Previous designs have been used to present a novel structure. A new multiplication algorithm is designed and simulated in 80 nm process. We used SPICE and some programming code for simulations. The latency has decreased by almost 15 percent and power consumption decreased by 14 percent. Our design reduced transistor count by 10 percent.
