Reversible Arithmetic Logic Unit Based on Bidirectional Gate: A Study
Main Article Content
Abstract
Reversible computing is an emerging paradigm that offers significant advantages in energy efficiency and reduced heat dissipation, making it particularly suitable for quantum computing, low-power VLSI design, and sustainable computing systems. This study investigates the design and implementation of a Reversible Arithmetic Logic Unit (RALU) based on bidirectional gate architecture. The proposed RALU leverages the unique properties of bidirectional gates to achieve functional versatility while minimizing energy loss. The design integrates key arithmetic and logic operations, ensuring reversibility without compromising computational efficiency. Key metrics such as quantum cost, gate count, and delay are analyzed to evaluate the performance of the proposed RALU. Comparative analysis with conventional and other reversible ALU designs demonstrates its superiority in terms of reduced complexity and improved efficiency. This study also highlights the potential applications of the proposed RALU in fields such as cryptographic computing, quantum processors, and next-generation low-power systems.
