A program is executed on this CPU with base CPI of $2$ cycles and cache miss penalty of $60$ cycles. It is measured that the I$-$cache miss rate is $0\mathrm{.}03,$ and the D$-$cache miss rate is $0\mathrm{.}06.$ In addition, $15\%$ of the instructions executed are load instructions and $10\%$ are store. The write policy of the D$-$cache is write$-$through with allocate on miss. The probability of the write buffer being full is $0\mathrm{.}06.$

What is the average miss penalty for a d$-$cache miss incurred by store instructions?

What is the average CPI for instructions that are neither load nor store?

What is the average CPI for load instructions?

What is the average CPI for store instructions?

What is the average CPI for all instructions?

Round the answers to the nearest hundredth and separate them with commas. Make sure there are two decimal places in each answer even if both are zero. For example, if the answer is $1,$ it should be written as $1\mathrm{.}00.$

Correct Answer: $63\mathrm{.}60,3\mathrm{.}80,5\mathrm{.}60,5\mathrm{.}82,4\mathrm{.}27$
