Fast Fourier Transform for the Xtensa HiFi4

[erikraynolds]

Hello guys,

I would have some simple request and looking for a sample code for the high performance DSP application on the Xtensa/HiFi4 microprocessor with the Fast Fourier Transform (FFT). Can you please point me where I could find some?

Thank you very much.
