For the system in problem 4, suppose a main memory access requires 30ns, the page fault rate is .01%, it costs 12ms to access a page not in memory (this time includes the time necessary to transfer the page into memory, update the page table, and access the data). Also suppose a TLB hit requires 7ns, the cache miss rate is 3%, the TLB hit rate is 95%, a cache hit requires 15 ns. On a TLB or cache miss, the time required for access includes a TLB and/or cache update, but the access is not restarted. On a page fault, the page is fetched from disk, all updates are performed but the access is restarted . All references are sequential (no overlap, nothing done in parallel)

a.) Calculate the time for a TLB hit and a cache hit.

b.) Calculate the EAT (effective access time) for a TLB hit.
