A Novel VLSI Architecture for Reversible ALU Logic Gate Structure

Programmable reversible logic is emerging as a prospective logic design style for implementation in modern nanotechnology and quantum computing with minimal impact on circuit heat generation. Recent advances in reversible logic using and quantum computer algorithms allow for improved computer architecture and arithmetic logic unit designs. In this paper, the design reversible ALU based on different types of reversible gate used with minimal delay, and may be configured to produce a variety of logical calculations. The proposed reversible ALU based on DKG gates is verified and its advantages over the only existing adder design are quantitatively analyzed. The proposed design is synthesized using Xilinx ISE software and simulated using VHDL test bench.
