Question 1
What is the primary purpose of L1 cache?
- To store data long-term
- To minimize hit time
- To increase miss penalties
💡 Hint: Consider its direct connection to the CPU.
Question 2
True or False: The L2 cache is faster than the L1 cache.
- True
- False
💡 Hint: Recall the sizes and speeds of both caches.

Challenge Problems
Push your limits with challenges.
Question 1
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.
💡 Hint: Follow the original problem steps for miss calculation.
Question 2
Analyze how cache size affects miss penalties if L1 cache is increased. Discuss potential impacts on effective CPI.
💡 Hint: Think about how larger caches may slow access times down but increase storage.
