Problem 5[4 points]: Assume a computer with a processor that has the following characteristics: • CPI: 1 cycle Instruction miss rate: 1.5% • Data miss rate: 4.0% • Percentage of memory instructions: 30% • Miss penalty: 70 cycles • Hit time: 1 cycle You have the following 2 options to upgrade your computer: a) Double the processor frequency (and double its cache access time while the main memory stays the same). b) Make the main memory 2 times faster (while everything else stays the same). Which is a better choice? Why? You must show your work to get full credit.
