1. Draw the block diagram representation
2. From the following BDR you have drawn, estimate the execution time of the system using Intel 8086 Instruction Timing. Clearly show how you arrived at the answer.
3. Given a=b=c , estimate the new execution time of the system using Intel 8086 Instruction Timing. Compare your answer with question 2 and provide an explanation for the differences of your answer.
