Comparative Study of Approximate Multipliers [PDF]
Proceedings of the 2018 Great Lakes Symposium on VLSI, 2018 Approximate multipliers are widely being advocated for energy-efficient computing in applications that exhibit an inherent tolerance to inaccuracy. However, the inclusion of accuracy as a key design parameter, besides the performance, area and power, makes the identification of the most suitable approximate multiplier quite challenging.
