A CPU implemented in an analog modular synthesizer
This runs in the VCV Rack eurorack simulator.
I wrote a thread explaining the CPU on twitter
and a thread explaining just the ripple adder.
TODO list: #1
Here's the unannotated screenshot
and here's a video of the whole thing running
Instruction formats:
00000: no-op (clears bus)
10ooo: output ALU op to bus
010rr: load reg from bus (keeps bus)
110rr: output register to bus
0110n: load ALU operand (clears bus)
0111i: output immediate to bus
ooo = alu op
rr = register number
n = alu operand
i = immediate
Fetch and Decode
Data bus
3-Stage Clock
A single register
Register bank
Immediate value

Ripple carry adder
