Energy Efficient Approximate Multiplier Design for Image/Video Processing Applications

An energy-efficient approximate multiplier is designed by using an approximate compressor for image and video processing applications. This paper proposes an approximate 4:2 compressor design with an 18.75% error rate that consumes on an average 15% less energy compared with the existing designs from the literature. This paper proposes two variants of the multiplier, one with only approximate compressors and another one with approximate and accurate compressors.
