hi Mr Jeff, can you teach how to solved this question. I cannot understand how to calculate. I just start learning Computer Architecture Performance and i really not use to this subject. can you explain it very detail on how to calculate this.

Q 1 - " Suppose a computer spends frac used=90 of its time handling a computation when running a given program, and its manufacturers make a change that improves its performance on that type of computation by a factor of 10. If the program originally took 100 s, what will its execution time be after the change? "

Q 2 - " When run on a given system, a program takes 1, 000, 000 cycles. If the system achieves a CPI of 40, how many instructions were executed in running the program? "

THANKS MR JEFF
