Question: Consider a program that can execute with CPI = 1 if we could magically service every load instruction within 1 - cycle ( L 1

Consider a program that can execute with CPI =1 if we could magically service every load instruction within 1-cycle (L1 cache hit).
Now in practice, 9% of all load instructions suffer from an L1 cache miss, 6% of all load instructions suffer from an L2 cache miss, and 3% of all load instructions suffer from an L3 cache miss (and are serviced by the memory system).
An L1 cache miss stalls the processor for 8 cycles while the L2 is looked up. An L2 cache miss stalls the processor for 25 cycles while the L3 is looked up. An L3 cache miss stalls the processor for 200 cycles while data is fetched from memory. What is the CPI for this program if 35% of the program's instructions are load instructions? (Assume these delays add, i.e. the worst case stalls for 8+25+200 cycles.)
