Question 1.
What does TLB stand for?
Show hintHide hint
Think about the role of TLB in memory translation.
Question 2.
Define a cache hit.
Show hintHide hint
Is accessing data fast or slow if you have a cache hit?
3Question 3.
What happens during a TLB miss?
- Data is obtained directly from cache
- Main memory must be accessed
- Virtual addresses are ignored
Show hintHide hint
Think about where the CPU goes to find missing information.
4Question 4.
True or False: Virtually indexed caches avoid TLB access on cache hits.
- True
- False
Show hintHide hint
What is the main benefit of accessing cache directly via virtual addresses?
Question 5.
In an architecture using virtually indexed, physically tagged caches, if two virtual addresses point to the same physical address due to aliasing, how could this impact program execution?
Show hintHide hint
Consider what happens if two programs share the same data space.
Question 6.
Design a strategy to mitigate TLB misses in a high-performance computing environment.
Show hintHide hint
Think about hardware improvements or algorithms to optimize memory access.
