7. Explain about instruction, fetch, and decode cycles for a memory reference instruction. Draw a flow chart also to explain the same. Indicate clearly where and which processor registers comes into picture. Now let us assume while a instruction is in the middle of its decode cycle a interrupt is arrived. What is going to happen? Is the instruction is completed or not. If we want to stop there itself and handle the interrupt what are the difficulties? [16]
