An integral part of FFT computation are the twiddle factors, which, in software implementations, are typically stored into RAM memory implying large memory footprint and power cons...
A fundamental question of longstanding theoretical interest is to prove the lowest exact count of real additions and multiplications required to compute a power-of-two discrete Fo...
Abstract. Low-power design became crucial with the widespread use of the embedded systems, where a small battery has to last for a long period. The embedded processors need to efï¬...
In this article, we present a parallel implementation of a 1024 point Fast Fourier Transform (FFT) operating with a subthreshold supply voltage, which is below the voltage that tur...
- In this paper, the grouped scheme is specially applied to compute the fast Fourier transform (FFT) when the portions of transformed outputs are calculated selectively. The groupe...
