Assume that your cache has 2% miss rate for instruction memory and 4% miss rate for data memory. The miss penalty for instruction memory cache is 100 cycles and for data memory cache is 200 cycles. The base CPI is 1 cycle. Assume that you have a code which contains 200 instructions and 40% of them are load and store instruction, rest of them are R type of arithmetic instruction. What is the total clock cycle to execute the code? Hint: The question is asking the TOTAL clock cycle, not average CPI.
