You need help with the following question:

Question : You have a 2-level cache. Level 1 cache is 1MB and level 2 cache is 2MB. Level 1 cache has a mean access time of 20 nsec, level 2 200 nsec, and cache misses 10 µsec. L1 cache got 10,000 cache hits, L2 cache got 90 cache hits and there were 10 double-cache misses.

a) Calculate the hit-ratio for level-1 cache to 4 significant digits

b) Calculate the hit-ratio for level-2 cache to 4 significant digits

c) Calculate the mean access time to 4 decimal digits. Assume pipelining. i.e., we begin memory accesses while initiating cache accesses
