In the SRM and SLM instructions, both the operand R[SA] and the shift amount ield OP are checked to see if either is 0 before the shifts begin.

(a) Redraw the state machine diagram for these operations with these checks removed.

(b) Use the original diagram and the new diagram to compare the number of clock cycles required for values of OP equal to 0 through 7. Assume that the probability of each OP value for 1 through 6 is 1/8, for 0 is 1/4, and for 7 is 0. Assume that the likelihood of a 0 operand is 1/8. Perform calculations to determine the best implementation (with checks or without checks)
based on the given probability information and comparative number of clock cycles for the two implementations. Provide a convincing argument for your selected answer.
