HIGHLY EFFICIENT MULTIPLIER DESIGN WITH ADJUSTABLE TRUNCATION FOR POWER SAVING

Abstract

In various applications, multipliers play a crucial role, demanding substantial power consumption due to frequent multiplication operations. To address this, this Project propose an adjustable approximate multiplier that dynamically truncates partial products to balance accuracy, energy efficiency, and performance. Our approach includes a high-accuracy 4-2 compressor and a flexible error compensation circuit, allowing users to tailor accuracy and power consumption based on specific requirements at runtime. Experimental results showcase a notable reduction in delay and in average power consumption compared to the conventional Wallace tree multiplier.
