Research ArticleOpen accessIn the keywordsLow Power Hardware Implementation of High Speed FFT CoreM. Kannan, S. K. SrivatsaApplications based on Fast Fourier Transform (FFT) such as signal and image processing require high computational power. This paper proposes the implementation of radix-4 based parallel-pipelined Fast Fourier Transform processor which incorporates a low power commutator, butter-fly with multiplier-less architecture. The proposed parallel pipelined architectures have the advantages of high throughput and low power consumption. The multiplier-less architecture uses shift … …Journal of Computer Science, Vol. 3, Issue 6 · 30 Jun 2007 · 7,227 accessesView PDFCite
