A question about CPU Control Unit

[Hornet]

Hi, i'm not sure if this is the right place, but anyway i'd like to know something about modern CPU control unit.

In CPU, we have those fetch, decode, dispatch, scheduler and units like that. I'd like to know are those units considered part of the CPU control unit? Or are then not and that the CU just merely generate control single to those components?

From what I search online, many state that control units handles instructions decoding and stuff like that (before the instructions is executed in the FPU/ALU.) But they did not state if the hardware for the unit doing the decoding all is part of the control unit itself (or not).

Any help please? thanks alot...

This sounds like homework.

This sounds like homework.

lol, indirectly, its related to an assignment.

We're suppose to discuss about Control Unit design for multi-core processors. However what we learn in our text book doesn't covers this far. We only learn about how a CU controls the bus to memory, MBR, MAR, ALU and stuff like that. Its like a very simplified concept, where the instruction is fetch into MBR and straight to ALU, no any decoding stuff.

Now dealing with modern multi-core CPU, i don't know where all this decoders and schedulers fits in
