REALIZATION OF LOW POWER AND EFFICIENT SEQUENTIAL CIRCUITS USING REVERSIBLE LOGIC GATES

Reversible computing is a computational model that seeks to reduce energy dissipation by guaranteeing that the computational process is reversible. Every circuit performs reversible computing which maps to a distinct output and allows the input to be rebuilt from the output. We proposed optimized versions of sequential circuits using reversible logic gates, such as Peres and URG gates and performed simulations to analyze their behavior. These improved gates are more effective for usage in larger reversible circuits because they show optimal outputs while retaining their reversible characteristics. Later reversible flip-flops are designed with optimized reversible gates. Additionally, our study investigates the use of reversible logic in the context of shift registers, which are crucial parts of digital circuits used for data manipulation and storage. Reversible shift registers using the improved reversible gates are designed. To maintain data integrity, these reversible shift registers have optimal results compared to their traditional equivalents. We thoroughly examined and compared the suggested reversible implementations of shift registers and flip-flops regarding constant inputs, garbage outputs, and power dissipation. In conclusion, optimizing reversible gates and using them to create essential digital components is included. The suggested methodologies and approaches facilitated the development of reversible computing systems that are more economical and efficient
