Resolved! Can the FMAC implement a decimating FIR filter automatically? (can the yet-to-be released STM32U5 FMAC do this)?
If I have a signal sampled at 16384/32768Hertz, but I am only interested in frequencies below 2000Hz - can I use the FMAC to automatically produce a buffer of FIR filtered samples at 4096Hz? I think some hardware filter accelerators have a decimation...
