A new ALU architecture design using reversible logic
Arindam Banerjee, Debesh Kumar Das · 2016
A new ALU design scheme using reversible logic has been reported in this paper. In digital calculators, mathematical computations like addition, subtraction, different logic operations are frequently used. Here our intention is to use reversible logic to produce outputs of different arithmetic and logic operations on the same line which is a new idea. In this paper the proposed ALU design is based on two different addition methodologies. At first the technique has been verified using FPGA and then implemented using reversible logic. In contrast with the recently reported architectures, our design offers better performance in respect of area, delay and power as well as line count and quantum cost also. The quantum cost optimization for the proposed structure has been performed using well known NCV and NCV-|v1> libraries.
