Hello,

no, it won't make it easier or more difficult ; it's just a better split 
between acia and ikbd, with proper serial protocol, but the whole hd6301 
emulation is not really impacted by this.

I don't think DSP and CPU are using such simple interfaces as the one in 
the acia. It only supports very low bit rate between "old" 8 bit 
compoonents, there're better way to link modern components like a cpu 
and a dsp (but I didn't look at the dsp datasheet, maybe I'm wrong)
