Abstract: The need for energy-efficient computer arithmetic systems is growing day by day, and approximate computing is crucial to their design in terms of delay, power, and area for error-resilient systems. This paper introduces a new 3-bit approximate adder, followed by the proposal of a 4-2 approximate compressor using this approximate adder. Subsequently, two 8-3 approximate compressors are designed with the proposed 4-2 approximate compressor and OR-based logic. Finally, two 8-bit approximate Dadda multipliers and higher bit approximate multipliers are designed using the proposed 8-3 approximate compressors. The proposed 8-bit multiplier with the lowest dissipation provides improvements in PADP (power-area-delay product) and ADP (area-delay product) of 86% and 68.25%, respectively, when compared to the exact multiplier. The proposed multiplier's efficacy is assessed in an image-blending application, yielding blended images with average high structural similarity. According to extensive simulation data and figure of merit (FoM), the proposed multipliers architectures are a better option for error-resilient systems than the reported approximate multipliers.
