[HELP] FFT Example for ezDSP C5535

Hello,

I'm going to implement FFT on ezDSP C5535, but i don't know where to find examples for this problem. Have anyone had an example or give me an advice how to start?

Thank you in advance!

    I guess you want to use the HWA FFT. There is SW interface for that in the chip ROM, but see the errata related to the ROM code (doc SPRZ373B). You may opt to use the patched ASM files you find in a ZIP file mentioned there.
    The FFT implementation using the HW FFT is quite thoroughly discussed in the C5535 TRM (doc SPRUH87D). In TRM chapter 2.6 there is the skeleton of the simple SW needed to perform a 1024 point FFT.
