Question $3(15$ Points$)$ In a machine M$1$ clocked at $100$MHz$,$ it was observed that $20\%$ of the computation time of the Spec$2000$ integer point benchmarks was spent in the subroutine Multiply$($A$,$ B$,$ C$)$ that multiplies integers A and B and returns the result in C$.$ Furthermore, each invocation of Multiply$()$ takes $800$ cycles to execute. To speed up the program it is proposed to introduce a new instruction MULT to improve the performance of the machine on Spec$2000$ benchmarks. Please answer the following questions if you have enough data. If there is not enough data, simply answer $$Not enough data$.3\mathrm{.}1$ How many times is the Multiply$()$ routine executed in the set of Spec$2000$ programs?
