Nandini S M, K. Lakshmi Sudha · 2024
Multiplication operations form the backbone of various computational tasks, making the design of efficient multipliers a key focus in digital circuitry. High-speed, less area, and power-efficient multipliers are in demand for applications like neural networks and multimedia. This research paper explores Inexact Signed Wallace Tree Multipliers with Reversible Logic. The study investigates the synergy between inexact arithmetic and reversible logic, aiming to optimize both precision and energy efficiency. In this work, we present a comprehensive analysis of existing methodologies and challenges related to multiplier designs, highlighting the shortcomings and areas for improvement. Leveraging the versatile nature of reversible logic gates, we propose innovative techniques to enhance the efficiency of the Wallace Tree Multiplier architecture. By integrating inexact arithmetic principles, a dynamic precision adjustment mechanism is introduced, ensuring accuracy while minimizing computational cost. The system developed showcases remarkable gains in terms of speed and area.
