The five steps in the fetch/execute cycle and how do they correspond to a restaurant

The five steps in the fetch/execute cycle are:

1) Instruction Fetch (IF) - This starts with the moving from the memory to

the control unit which is given by the program counter. T he control unit

can then access the data immediately from the memory.

2) Instruction Decode (ID) - what task the system has to do, where the

results is to be stored and what operation is to be performed by which

data.

3) Data Fetch (DF) - it gets the value from the memory.

4) Instruction Execute (IE) - The particular instruction is executed.

5) Result Return (RR) - The Result Value is restored in a

particular memory location. T he return of new data resulting from

(EX) that is put back into memory.
