GA144

Simulator for the GreenArrays GA144

Status

Just starting out ...

Raison d'être

GreenArrays' GA144 is a wonderfully idiosyncratic microprocessor:

  • fully asynchronous logic
  • 32 orthogonal instructions
  • 64 words of RAM and ROM
  • 18 bit 'word'
  • 144 on-chip cores in a rectangular array

all of which conspire to make a software simulation relatively straightforward. And fun :-).
