The verilog code together with cocotb testbench of BFU unit of a DIF FFT processor. The module supports 16-bit word with Q8 fixed point format (can be changed). However, if you look at the inputs {a, ...
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 ...

Abstract: A radix-2/16 decimation-in-frequency (DIF) fast Fourier transform (FFT) algorithm and its higher radix version, namely radix-4/16 DIF FFT algorithm, are proposed by suitably mixing the radix ...
Abstract: An improved radix-16 decimation-in-frequency (DIF) FFT algorithm is proposed by introducing new indices for some of the output sub-sequences resulting from the conventional radix-16 DIF ...
