Performance Analysis of ALU design using Irreversible and Reversible gates
Now-a-days, the VLSI industry is tilting towards the application of reversible logic in the designing. Certain constraints like quantum cost, power dissipation and efficiency in producing the outputs mandates to employ the reversible logic gates over the irreversible logic gates.By deploying the logic which can be reversed , the generation of flaw outputs causing loss of information bits are eliminated. In this paper, we design an ALU holding restoring output logic gates and compare it with an ALU employed irrevocable logic gates. COG gate and HNG gate are the restoring logic gates mooted in developing the proposed design. The factors like average power, quantum cost are analyzed in this paper.
