Previous parts are available here, and I'd recommend they are read before continuing. Memory Operations We already have a small RAM which holds our instruction stream, but our TPU ISA defines memory read and write instructions, and we should get those instructions working. It's the last major functional implementation we need to complete. The fetch stage is simply a memory read with the PC...
