32-BIT FPGA BASED ALU EMPLOYING REVERSIBLE LOGIC

Project Code :TVMAFE627

Objective

Power efficiency: Reversible logic can help reduce power consumption by allowing for easier energy recovery

Abstract

The ALU, a crucial component in processors, serves arithmetic and logical functions, essential in digital system design. This study presents a 32-bit ALU designed in Verilog HDL using logical gates like AND and OR for each one-bit ALU circuit, accommodating 16 operations. This design operates faster and consumes less power than traditional ALU processors. Reversible logic, gaining importance for its power reduction capability, plays a significant role in low-power VLSI design. The paper introduces an ALU implementation based on reversible logic, comparing it to a conventional ALU architecture. The method's effectiveness is demonstrated through synthesis and simulation using Xilinx VIVADO.

Keywords:- Reversible gate, Verilog HDL, Feynman gate, Peres gate, Toffoli gate, Fredkin gate, Arithmetic Logic Unit.
