Question 1.
What is the primary function of a cache in a CPU?
Show hintHide hint
Think about why fast access is important in CPU processing.
Question 2.
Define L1 and L2 caches.
Show hintHide hint
Consider their locations and role in the hierarchy.
3Question 3.
What is the primary purpose of L1 cache?
- To store data long-term
- To minimize hit time
- To increase miss penalties
Show hintHide hint
Consider its direct connection to the CPU.
4Question 4.
True or False: The L2 cache is faster than the L1 cache.
- True
- False
Show hintHide hint
Recall the sizes and speeds of both caches.
Question 5.
Given a CPU with a primary cache miss rate of 2% and main memory access time of 100 ns, compute the effective CPI when a L2 cache with a miss rate of 0.5% is added, assuming overheads.
Show hintHide hint
Follow the original problem steps for miss calculation.
Question 6.
Analyze how cache size affects miss penalties if L1 cache is increased. Discuss potential impacts on effective CPI.
Show hintHide hint
Think about how larger caches may slow access times down but increase storage.
