Question

FFT hardware accelerator for STM32H5

I’m interested in STM32H5 series (since it’s based on a M33 core which offers performance and security).

I need to execute FFT and FIR filtering functions in real time and so I’ve been investigating on hardware accelerators available on the MCU.

I see there are CORDIC and FMAC, but I don’t find a specific mention to FFT (like NXP does for PowerQuad).

So I wonder if they can be used to perform hardware-optimized FFT.

And I wonder if ST has some benchmarks (with sample code) for hardware accelerated FFT on STM32H5.

Thanks
