A Modified Twin Precision Multiplier with 2D Bypassing Technique

Abstract

This paper presents a twin precision multiplier with modified 2-D bypass Logic. The multiplier can perform one 8-bit multiplication or two 4-bit multiplications. The multiplier structure is modified by adding a 2-dimensional modified bypassing logic resulting in reduction in dynamic power as well the delay. Simulation results indicate that with a marginal increase in area, the proposed twin precision multiplier achieves an improvement of 25.5% in delay and up to 29% reduction of power-delay product when compared to existing designs.
