VLSI Design of Low Power Reversible 8-bit Barrel Shifter
Journal Title: The International Journal of Technological Exploration and Learning - Year 2013, Vol 2, Issue 6
Abstract
Nowadays reversible circuit designing is the emerging area of research. This design strategy aims towards the formation of digital circuits with ideally zero power dissipation. And also Reversible logic is gaining interest in the recent past Due to its less heat dissipating characteristics. A lot of research has been done in combinational as well as sequential design of reversible circuits. In this paper we have proposed a reversible fredkin gate which is better than the existing designs in the literature. A novel design of reversible 8-bit barrel shifter proposed in this paper. The important reversible gates used for reversible logic synthesis are Feynman gate, Fredkin gate, TSG gate and sayem gate etc.The transistorized implementation of reversible gate presented in this paper are completely reversible in nature i.e. it can perform both forward and backward computation.Layouts for each gate and power, delay,PDP and LVS done through Tanner EDA tools .
