2 cards from this section. Quick, good the night before a test.
What happens during a page fault?
Refer to what the OS does upon encountering a page fault.
Define a Cache Hit.
Think about the speed benefits of data retrieval.
What is a page fault?
Think about what happens when data is not found.
Is a cache miss faster to process than loading from a disk?
Consider the speed differences in memory accesses.
Given that page faults occur once every ten instructions in a system where the fault recovery takes 30 cycles, calculate the effective instruction time if a normal instruction takes 5 cycles.
Consider how to average the times for both occasions of normal instruction and page fault.
Explain how a TLB miss can escalate into a longer wait for data retrieval as it progresses through the memory hierarchy.
Envision the steps involved for each type of miss and the impact on overall data accessibility.
