Design and analysis of a hybrid encoded low power multiplier with reduced transition activity technique

Published: 26 February 2010 Publication History

Abstract

Multiplication is an arithmetic process that is mostly used in Digital Signal Processing (DSP) and communication applications. Efficient implementation of the multipliers is required in many applications. The design of hybrid encoded low power multiplier with Reduced Transition Activity Technique (RTAT) is presented in this paper. The proposed encoding technique reduces the number of switching activity and dynamic power consumption by analyzing the bit patterns in the input data. In this proposed encoding scheme, the operation is executed depends upon the number of 1's and its position in the multiplier data. The architecture of the proposed multiplier is designed using a low power full adder which consumes less power than the other adder architectures. The switching activity of the proposed multiplier has been reduced by 86% and 46% compared with conventional and Booth multiplier respectively. It is observed from the device level simulation using TANNER 12.6 EDA that the power consumption of the proposed multiplier has been reduced by 87% and 26% compared with conventional and Booth multiplier.
