Background I'm looking at Transport Triggered Architectures (also this), linked to from an OISC page listing many different 1-Instruction Set Computers. It basically says the following: TTA progr …

I am still trying to wrap my head around this, which shows how to simulate control-flow without using an if-statement. I've been looking at basic logic today and learned that you can represent all lo …
