Reversible logic has shown wide applications in emerging technologies such as quantum computing, optical computing, and extremely low power VLSI circuits.Recently, many researchers have focused on the design and synthesis of efficient reversible logic circuits.In this work, as an example of reversible logic sequential circuits, we propose a novel reversible logic design of the Universal Shift Register.Here, we proposed a D-flip-flop whose efficiency is shown in terms of garbage output, constant input and number of reversible gates.Using this D flip-flop, efficient universal shift register is proposed.Universal shift register is a register that has both right and left shifts and parallel load capabilities.The proposed designs were functionally verified through simulations using Verilog Hardware Description Language.
