mnasser431998/bfu_dif_fft_rtl

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, ...

Canonic real-valued FFT structures

Abstract: An N-point FFT processes N complex signals to compute N output complex signals using decimation-in-time (DIT) or decimation-in-frequency (DIF) approach. The FFT makes use of n = log 2 N ...
