Challenge Problems

Push your limits with challenges.

Question 1

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?

💡 Hint: Calculate the number of hits and misses based on the provided rates.

Question 2

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?

💡 Hint: Evaluate the workload types against the memory management strategy.
