CORDIC, FMAC and PSSI in stm32h72x 73x

[mach665]

The new STM32H72x and 73x serials have cordic coprocessor, filter math accelerator and parallel synchronous slave interface. Interesting for high speed ADC and DSP applications.

Yes. I just noticed that yesterday. Haven't used FMAC but seems it's got no performance advantage over ARM software (just releases the core to do something else parallel to the calculations). Is that your understanding? PSSI seems perfect to connect to a FTDI FIFO in master mode (used to need a FPGA to do that).
