Sorry this is probably a bit niche, but I was wondering if anyone has looked at using the DSP instructions?
I didn't even know the cortex-M4's had these instructions until I recently came across this audio library for the Teensy boards that uses them.
I'd love to be able to do some experimenting with these for audio projects from within Espruino too but I'm guessing it would be quite a lot of work to expose the DSP instructions from with Espruino?
