Reconfigurable Architecture Pipelined Power Efficient Fixed Width Baugh-Wooley Multipliers

Abstract

This paper presents a pipelined reconfigurable fixed-width Baugh-Wooley multiplier design framework that provides four configuration modes (CMs): n * n fixed-width multiplier, two (n/2 * n/2) fixed-width multipliers, (n/2* n/2) full precision multiplier and two (n/4 * n/4) full-precision multipliers will be carried out. In this work pipeline is reconfigarable to save the power. In this work low-power schemes including gated clock and zero input techniques are employed to achieve the power-efficient pipelined reconfigurable design. The presented power-efficient pipelined reconfigurable fixed width multiplier design not only generates a family of widely used multipliers.
