Dear Microprocessor Expert,

Please help me with this Question.Thanks.

A certain microprocessor supports the "addition". The instruction cycle is consisted of

"fetch", "execute" and "store" phases. For each instruction stored in the memory, control

unit performs the above three tasks.

i$.$ Write down the micro operations which take place during the "fetch",

"execute" $($of "add" operation$)$ and "store" phases. You should focus on the

different data, address and control signals passing between different

components. Consider instructions containing direct values to operate on and

the memory address of results storage.
