This paper deals with the multiplier using approximate 15-4 compressor. The proposed multiplier has overcome the problems of power and delay. We propose a multiplier using accurate and approximate (four designs) a majority of 15-4 compressors and its performance is compared with a multiplier which uses accurate and approximate 3-2, 4-2 as well as 15-4 compressors. Some of the basic compressors like 3-2, 4-2 are used in the reduction stage of multiplier to reduce the power and increase the performance. Basically, small size compressors are used in small size multipliers but for large size multipliers it takes more time and consumes more power. To overcome this problem, we go for large size compressors like 15-4 for 16 bits or 32 bits. Approximate 15-4 compressor is proposed using four different designs. The basic building block for the 15-4 compressor is a 5-3 compressor.
