16 BIT ALU DESIGN USING REVERSIBLE LOGIC

Reversible logic has emerged as one of the most important approaches for the power optimization with its application in low power VLSI design. It has wide applications in the field of, low power CMOS design, optical information processing and nanotechnology. Reversible logic is used to reduce the power dissipation that occurs in classical circuits by preventing the loss of information. This paper proposes a rewiew on design of a reversible ALU. The ALU consists of arithmetic and logical operations. The arithmetic operations include addition, subtraction and the logical operations include AND, OR, NOT and XOR. The degined ALU has better efficiency as it has less power loses and reduction in power loss upto 51 % is obtained
