Slow DSP processing #6

Closed MarkoSagadin closed 3 years ago

It seems that DSP processing takes too long. On mbed example it took less than 1 ms, as it printed 0ms, now it is printing 41 ms. We need to check if there are some incorrect settings.

CONFIG_FPU=y was missing, now time dropped from 41ms to 15ms for DSP part of inference
