An Arithmetic Logic Unit design based on reversible logic gates

In this paper, a design constructing the Arithmetic Logic Unit(ALU) based on reversible logic gates as logic components is proposed. By using reversible logic gates instead of using traditional logic gates such as AND gates and OR gates, a reversible ALU whose function is the same as the traditional ALU is constructed. The presented reversible ALU reduces the information bits' use and loss by reusing the logic information bits logically and realizes the goal of lowering power consumption.
