3Question 3.
What is a Translation Lookaside Buffer (TLB)?
- A structure that maps pages
- A fast cache for address translations
- A component in the CPU
Show hintHide hint
Think about the function of TLBs in memory management.
4Question 4.
True or False: Locality of reference indicates that data access is random.
- True
- False
Show hintHide hint
Remember how programs access memory in practice.
Question 5.
Consider a hypothetical system where the TLB contains 64 entries and has a hit rate of 95%. If a process accesses 1 million pages, how many accesses would be fulfilled by the TLB, and how many would result in a miss penalty?
Show hintHide hint
Calculate the number of hits and misses based on the provided rates.
Question 6.
In a scenario where a system implements a random replacement strategy for the TLB, discuss the potential consequences of this strategy when working with different workloads. What might be the pros and cons?
Show hintHide hint
Evaluate the workload types against the memory management strategy.
