Reversible logic is promising as it is able to compute with various applications in very low power like nano-computing for example quantum computing. Reversible circuits are like conventional circuits despite these are build from reversible gates. Reversible circuits, have single, one-to-one mapping between the input and output vectors. Conventional digital circuits dissipate a significant amount of energy because bits of information are erased during the logic operations. Reversible logic units are required to recover the state of inputs from its outputs. Low power is challenging work in processor design. One of the most basic operational units in the processor is an Arithmetic and Logical Unit (ALU). Arithmetic and Logical Unit (ALU) is a critical component of a microprocessor and is the core component of central processing unit. This paper describes the design technique for low power, low area Arithmetic and Logical Unit (ALU) design. Reversible logic is special optimization technique having its application in low power design. Simulation of circuits is done by ISE Simulator and language used for programming is very high speed hardware integrated circuit hardware descriptive language (Verilog).
