8.3 a. Consider a CPU with two parallel integer execution units. An addition instruction requires 2 clock pulses to complete execution, and a multiplication requires 15 clock pulses. Now assume the following situation: the program is to multiply two numbers, located in registers R2 and R4, and store the results in R5. The following instruction adds the number in R5 to the number in R2 and stores the result in R5. The CPU does not stall for data dependencies, and both instructions have access toa values of R2, R4, and R5 assume that the CPU does handle data dependencies correctly. What is the result? If we define wasted time as time in which an execution unit is not busy, how much time is wasted in this example? are 3, 8, and 0, respectively. What is the result? Novw
