It's ironic that Ditzel went from Berkeley RISC to Bell Labs and helped develop CRISP [1]. This was the invention of the Decoded Instruction Cache which solved the fetch/decode bandwidth problem. You could have a CISC and not have to worry about decode bandwidth. You could have a wide μop and not have to worry about fetch bandwidth.
