$($c$)$ Consider a CISC microprocersor whose machine cycle is shown below:

i$)$ How many segments does the processor have?

II$)$ How many dock cycles are required for each segment to complete its tark?

iii$)$ Using a space$-$time diagram, determine the number of clock cycles that are

required to complete $4$ tarks:

iv$)$ Calculate the speedup for $100$ instructions. Assume $L_n=t_{f.}.$
