Efficient radix-4 FFT on StarCore SC3000 DSPs

The Fast Fourier Transform (FFT) is a widely used algorithm that computes the Discrete Fourier Transform (DFT) using much fewer operations than a direct implementation of the DFT. FFTs are of great ...

Efficient VLSI Architecture for Decimation-in-Time Fast Fourier Transform of Real-Valued Data

Abstract: The decimation-in-time (DIT) fast Fourier transform (FFT) very often has advantage over the decimation-in-frequency (DIF) FFT for most real-valued applications, like speech/image/video ...

Modified SDF Architecture for Mixed DIF/DIT FFT

Abstract: In this paper, we propose the modified Single-path Delay Feedback (SDF) architecture for FFT implementation, which implements a mixed Decimation-in-Frequency (DIF) / Decimation-in-Time (DIT) ...
