Wow. What a fantastic post! I had question about the following passage:
>"As you can see, the CPU performs many activities in parallel for one microinstruction, which increases the computer's performance."
Would this microcode also be considered one of the first forms of ILP(instruction level parallelism) then?
- kens 5y agoIt's still executing a single instruction, so it's not ILP. Multiple functional units can do different parts of the instruction in parallel, but instructions are still sequential. The System/360 Model 91, a more advanced model, used instruction level parallelism for higher perormance.
- kragen 5y agoI forget, did Stretch have ILP?
