Abstract :

This study delves into the realm of approximate computing, where computational errors and imprecisions are embraced as acceptable trade-offs to achieve more efficient and resource-conserving solutions. The research focuses on the design of approximate adders within the framework of Quantum-dot Cellular Automata (QCA), a promising technology for ultra-low-power computation. Approximate adders are circuits that introduce controlled errors into addition operations to reduce resource consumption while maintaining adequate precision. Two distinct approaches are explored in this study: the utilization of threshold gates and the adaptation of Arithmetic Logic Units (ALUs) to create QCA-based approximate adders. These approaches aim to strike a balance between precision and computational resources, ultimately offering more energy-efficient solutions. Additionally, novel majority inversion-based approximate adder architecture is proposed, emphasizing significant area reduction. The study's findings shed light on the potential of approximate computing in QCA-based systems, paving the way for simplified, energy-efficient, and error-tolerant computational solutions.
