Display frequency spectrum - Simulink - MathWorks
https://www.mathworks.com/help/dsp/ref/spectrumanalyzer.html
The Spectrum Analyzer block, referred to here as the scope, displays the frequency spectra of signals. You can use the Spectrum Analyzer block in models running in Normal or Accelerator simulation modes. You can also use the Spectrum Analyzer block in models running in Rapid Accelerator or External simulation modes, with some limitations.

Pull requests. Spectrum analyzer system using a 512-point FFT, in a Cyclone IV FPGA. Reads i2s audio from the codec and then does all FFT/VGA functions. Nios just reads the FFT result and draws the display bars. VGA frame buffer on-chip. VGA signals generated on-chip. See the included video files to watch it in action.
