On the Analysis of Reversible Booth´s Multiplier

Reversible logic attains the attraction of researchers in the last decade mainly due to low-power dissipation. Designers´ endeavors are thus continuing in creating complete reversible circuits consisting of reversible gates. This paper presents a design methodology for the realization of Booth´s multiplier in reversible mode. Booth´s multiplier is considered as one of the fastest multipliers in literature and we have shown an efficient design methodology in reversible paradigm. The proposed architecture is capable of performing both signed and unsigned multiplication of two operands without having any feedbacks, whereas existing multipliers in reversible mode consider loop which is strictly prohibited in reversible logic design. Theoretical underpinnings, established for the proposed design, show that the proposed circuit is very efficient from reversible circuit design point of view.
