Abstract

This article presents energy efficient fused multiplyadd for multimedia applications. Low cost, low power and high performance factors diddle the design of many microprocessors directed to the low-power figuring market. The floating point unit occupies a significant percentage of the silicon area in a microprocessor due to its wide data bandwidth and the area occupied by the multiply array. The fused floating-point multiply-add unit is utilitarian for digital signal processing (DSP) applications such as fast Fourier transform (FFT) and discrete cosine transform (DCT). The proposed designs are implemented for single precision and synthesized with a 45-nm standard cell library. To improve the performance of the fused floating point multiply-add unit, we are supervening upon leading zero anticipation with the novel leading zero detection, as the novel leading one detection algorithm allowing us to significantly reduce the anticipation failure rates.
