b)Consider the “in-order-issue/in-order-completion” execution sequence shown in
Figure 2.2. Identify the most likely reason why I2 could not enter the execute
stage until the fourth cycle. Evaluate if “in-order issue/out-of-order completion”
or “out-of-order issue/out-of-order completion” will fix this. Justify your answer.
