This was a final project in a VHDL course ar AGSTU. From the documentation:
Fast Fourier transform is ubiquitous in digital signal processing, in this project an analogue audio signal from a I2S connected AD-converter is processed using techniques such as windowing, overlapping frames, then a FFT is taken, frequency power is calculated and represented on a VGA monitor. The design includes several custom components and third party IP cores, the design is validated and verified on an FPGA.
The design has been run on a intel MAX10 FPGA. For an FFT dblclockfft is used.
