Poster: Energy-Efficient Inexact Speculative Adder with High Performance and Accuracy Control

Approximate circuit design is a promising approach to improve performances and energy efficiency beyond the boundaries of conventional digital circuits. Such strategy is suitable for error-tolerant applications involving perceptive or statistical outputs. This work presents a novel architecture of an Inexact Speculative Adder for high-performance applications with optimized hardware and advanced error compensation technique. This adder allows precise tuning of accuracy to match design specifications while optimizing performances and energy efficiency. It demonstrates power savings up to 26% and energy-delay-area reductions up to 60% compared to the state-of-the-art.
