Question 1.
What is a cache miss?
Show hintHide hint
Think about why we use cache memory.
Question 2.
Name the three types of cache placement.
Show hintHide hint
Consider how each type defines memory block storage.
3Question 3.
What is the effect of increasing associativity in caches?
- Increased hit rates
- Decreased hit rates
- No effect
Show hintHide hint
Consider how flexibility influences performance.
4Question 4.
A fully associative cache allows a memory block to be placed in any line. True or False?
- True
- False
Show hintHide hint
Think about the freedom of placement in this type of cache.
Question 5.
Discuss the trade-offs one might consider when designing a cache system that prioritizes speed over space.
Show hintHide hint
Consider performance metrics in parallel with hardware limitations.
Question 6.
Calculate the miss rate for a direct-mapped cache versus a fully associative cache given the same block access pattern.
Show hintHide hint
Remember to look at the access patterns and how they relate to the mapping.
