Digital System Design of ALU using Reversible Logic Gates

In the integrated circuit designs, the Area, Power dissipation and Time delay will play an important role. The Speed will rises with decreasing the size of a computing element and mean while heat dissipation will lowers with decreasing power dissipation. Future technologies for quantum computing will involve reversible logic, and reversible logic gates reduce leakage power usage. Reversible logic gates were used to design the arithmetic and logical unit (ALU) in this research work. Electronic unit such as ALU’s are built upon conventional or irreversible logic gates. Due to the saturation of Moore’s law, alternating ways are formed where new semiconductor materials and new methodologies have been implemented. One such way is to use reversible logic gates instead of irreversible logic gates. In this application of VLSI design, reversible logic has significantly emerged in power optimization technology. To validate functionality, each suggested design was analyzed and simulated using cadence virtuoso.
