3 cards from this section. Quick, good the night before a test.
What is a page table?
Think about how memory addresses are managed.
Describe what a TLB does.
Remember its role in address translation.
What is the primary purpose of a page table?
Think about how virtual memory works.
True or False: A TLB can reduce the need to access main memory frequently.
Remember the caching effect.
A CPU needs to process 1 million page table entries and uses a TLB, yet registers 0.01% miss rates. If the TLB hit time is 1 nanosecond and miss penalty is 50 nanoseconds, compute the average time for address translation.
Think about how often the TLB hits versus misses and calculate their respective time contributions.
Discuss the efficiency of managing a page table with 524288 entries versus 256 when considering a hardware implementation in a system that requires frequent context switches.
Reflect on how larger tables impact context switch time and processing efficiency.
