Low-power fixed-width array multipliers

Abstract

A fixed-width multiplier using the left-to-right algorithm for partial-product reduction is presented. The high-speed feature offered by this design is used to trade for low power. In one design, the proposed multiplier not only owns 8% speed improvement but also gains 14% power and 13% area reduction. When applying the voltage scaling to balance the speed, the power reduction is increased to 29%.
