Question 1.
What is a TLB and its purpose?
Show hintHide hint
Think about what happens when the CPU accesses memory.
Question 2.
Define the synonym problem in caching.
Show hintHide hint
Consider how this might affect cache coherence.
3Question 3.
What is the main advantage of VIPT caches over VIVT caches?
- A. They do not require a TLB.
- B. They allow for concurrent access of cache and TLB.
- C. They work with only physical addresses.
Show hintHide hint
Think about the access times in cache designs.
4Question 4.
True or False: The synonym problem causes cache flushing during context switches.
- True
- False
Show hintHide hint
Recall the need for coherence in caching.
Question 5.
Consider a scenario where a VIPT cache is implemented in a system with a context switch occurring frequently. How would the performance be impacted, and what measures would you take to mitigate issues?
Show hintHide hint
Think about measures that could smooth process transitions.
Question 6.
You are tasked with designing a new cache system. Discuss how you would incorporate VIPT and page coloring to prevent the synonym problem. What factors would you consider?
Show hintHide hint
Explore how design choices impact overall functionality.
