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 :-).
