Question: Consider a memory paging system, where the page table is stored in memory as well. The system in question is also equipped with a TLB.

Consider a memory paging system, where the page table is stored in memory as well. The system in question is also equipped with a TLB. It takes 2 nanoseconds to look up a page table entry in the TLB. Memory access time is 200 nanoseconds. What is the effective memory access time of an operation that reads a word of bytes from a virtual address that refers to a location in memory, if 75% all page-table references are found in the TLB?
