Hi, I'm looking for info about the performances of the FMAC coprocessor in STM32G4 series. Surprisingly enough, I couldn't find any specification on the subject neither in the datasheet, nor in the reference-manual.

I suppose FMAC uses AHB clock. I would like to know, if possible, how many clock cycles are required to perform a multiply-and-accumulate step in a FIR or IIR filter.Thank you for your help
