| Question 12 |
Consider a single-level page table system, with the page table stored in the memory. If the hit rate to TLB is 80%, and it takes 15 nanoseconds to search the TLB, and 150 nanoseconds to access the main memory, then what is the effective memory access time, in nanoseconds?
| 185 | |
| 195 | |
| 205 | |
| 175 |
Question 12 Explanation:
Effective memory access time =0.8(15+150)+0.2(15+150+150)
=132+63
=195 ns
=132+63
=195 ns
Correct Answer: B
