Abstract
Today in nanometer regime, approximate circuits have attracted much more attention due to the pursuit of low power consumption and high performance. Approximate multiplier is the key arithmetic function in many error-tolerant applications such as signal processing. In this paper, two approximate compressors based on input reordering logic have been proposed for the partial product reduction in the multiplication. A 2-bit reordering circuit is also designed for the proposed multiplier. Experimental results show that the proposed multiplier sacrifices only a small amount of precision (about 0.58%) to drastically reduce power, area, and delay up to (36.6%), (28.8%) and (20.1%) compared to accurate Wallace multiplier. The proposed multiplier achieves a high signal-to-noise ratio (over 50dB) when applied to an image processing algorithm.
