Consider the execution sequence “in-order-issue /in-order-completion” shown in the figure.1) Identify the most probable reason why I2 couldnot enter the execution stage until the fourth cycle. Could“in-order issue / out-of-order completion” or“out-of-order issue / out-of-order completion” fixthis? If so, what? 2) Identify the reason why I6does not enter the writing stage until the ninth cycle. Could“in-order issue / out-of-order completion” or“out-of-order issue / out-of-order completion” fixthis? If so, what?
