Hi, I am getting really stuck trying to find answers for these questions that I have been asked to do. I have already described the function of the fetch execute cycle but cannot find answers to this question:

Describe the relationship of the fetch-execute cycle to the workings of a microprocessor, making detailed reference to the role played by hardware and software in this relationship.

I have searched google, books and these forums and have found nothing that answers this question. I would really appreciate your assistance to this question.


Thanks,

Ian

Is this a school assignment?? We may be willing to help if it is, but we generally do not like it if that is not made extremely clear in the request...

Hi, its a college assignment, I have searched and searched and haven't found anything that is of use. Even my tutor hasn't provided any resources for me to use. I would be extremely thankful if someone could help me.

Thanks,
Ian

A microprocessor is usually a register in your CPU that decodes instructions.

There are CPUs that have complete hardware decoding, (meaning the wires are hardwired to the path in which the instruction is located, usually some ROM chip) and then there is a microprocessor which selects the path using SOFTWARE.

So with a microprocessor there is some hardware coding, and software coding.

Visit this webpage, its from my cpu architecture class. There are notes that go in much greater detail.

No, it is not. Maybe you mean microsequencer?
A microprocessor is a CPU on a single chip.

You are correct, I was confused.
