Objective

The objective of this project is to design and analyze different adder circuits using reversible logic gates for low-power and energy-efficient computation. It focuses on implementing adders such as ripple carry, carry look-ahead, and carry save using reversible gates to minimize information loss. The design will be simulated to evaluate parameters like delay, power consumption, and gate count. Reversible logic is applied to achieve reduced heat dissipation and improved performance in digital circuits. The overall goal is to develop optimized adder architectures suitable for future low-power and quantum computing applications

Abstract

The design and analysis of efficient adders are crucial for enhancing the performance of digital systems, particularly in arithmetic and signal processing applications. This paper presents the comparison of two different types of adders Ripple Carry Adder (RCA), Carry Increment Adder (CIA) ,Carry Save adder(CSA),Carry Select Adder(CSLA),Carry Skip Adder(CSKA) using Reversible logic gates, based on selection line it will reconfigurable. Reversible logic is an emerging computational model that offers reduced power dissipation, which is a significant advantage in low-power digital circuit design. Each adder type is analyzed in terms of its logical structure, delay, area, and power consumption, with the aim of identifying how reversible gates can optimize these parameters. The implementation of basic reversible gates such as the Toffoli gate, Peres gate and Haghparast and Navi Gate(HNG) gate in constructing the adders .Through simulation and performance metrics, this paper highlights the potential of reversible logic in reducing energy consumption and enhancing speed in arithmetic operations. The results suggest that reversible logic can provide a promising avenue for the development of energy efficient and high-performance adders in future digital systems. The analysis of different adders using reversible logic gates is synthesized in Xilinx Vivado.
