Nice. Still reading through it.
I like his definition of RISC. It captures the key points. Interesting that a
substantial fraction of those criteria apply to the CDC 6000 architecture, which some of
us like to call out as the first RISC architecture. Sure, it has only 3 x 8 registers,
but when registers are built up out of discrete transistors that's understandable.
The performance considerations that drive the RISC design approaches carry over quite
nicely.
