So the Nord used a DSP - case in point, it used a DSP which has hardware registers / accumulator, etc...designed for double floating point precision operations. That DSP had "Double precision 48 x 48-bit multiply with 96-bit result in 6 instruction cycles " - among other hardware support that even things like the M0, M3, and M4 just can't compete with. Don't just judge performance by MIPs.Still excited to hear it though - any videos?
I'd say that 48million 32x32bit multiplies per second go a long way.
At the moment I ported the sound engine to the Nano so that I can develop the scanboard and MIDI reception.
Not as good as the dsp-G1 having only 12-bit 10500Hz samplerate but very good for an ATmega328@16MHz.
It's the same dsp code.
