On: The DooM-chip: no CPU, no opcodes, no instruction ...

[Koshkin]

This feels like a breath of fresh air: too many FPGA applications today resort to implementing a simple CPUs (a.k.a. PSM - “programmable state machine”), and the required logic is implemented in its “machine code.”

I think you'd be surprised how many classic hardware designs take that approach as well. There's nothing wrong with that approach.
