WebThe simplest and perhaps best-known method for computing the FFT is the Radix-2 Decimation in Time algorithm. The Radix-2 FFT works by decomposing an N point time domain signal into N time domain signals each composed of a single point. WebWe decomposed the FFT power consumption such as an equation of 3 terms (equation(6)). PFFT = D(N).fMHZ+S(N)+λplan (6) For the 3 kinds of architecture, we obtained 3 models which are given by the equation (7), (8) and (9) respec-tively for a parameter range given by equation(10).
