Efficient Design and Analysis of N-bit Reversible Shift Registers

The biggest motivation to study reversible technologies is that, it is considered to be the best potential way to improve the energy efficiency than the conventional models. It has shown greater impact to have extensive applications in emerging technologies such as Quantum Computing, QCA, Nanotechnology and Low Power VLSI. In this paper, we have realized some new designs of several types of registers including universal shift register up to N-bit and a dynamic register. We have also analyzed the cost metrics of these structures in tabular form and also with some lemmas. While approaching for universal shift registers we have demonstrated a novel design of reversible multiplexer which is discussed in terms of an algorithm.
