Designing of Low Power Low Area Arithmetic and Logic Unit

Ajay Kumar Sharma, Anshul Jain

Low power is challenging work in processor design. Implementing power optimization on all components of the processor is main issue in designing. One of the most basic operational units in the processor is an ALU. 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 logic unit design. The ALU is one of the most frequently accessed modules in a CPU and is utilized during most instruction execution. The power consumption is main issue in designing. In our paper low power ALU design using reversible logic. Reversible logic is special optimization technique having its application in low power design. In our paper number of gate and power are reduced .The area of design also reduced in our proposed design.
