Question 1
What is the primary purpose of multi-level caches?
- To increase execution speed
- To increase chip size
- To reduce power consumption
💡 Hint: Think about how caches improve the flow of data.
Question 2
True or False: Out-of-order execution can improve performance by allowing dependent instructions to run simultaneously.
- True
- False
💡 Hint: Recollect how dependencies influence execution flow.

Challenge Problems
Push your limits with challenges.
Question 1
If a CPU has a 3% miss rate on L1 and a 0.1% on L2, with a main memory access latency of 200 nanoseconds, calculate the effective CPI assuming L1 takes 1 cycle to fetch data.
💡 Hint: Convert all timings to cycles using the clock rate.
Question 2
Design a comparison of two different cache architectures and analyze their performance regarding CPI reduction.
💡 Hint: Use empirical data and assumptions made during lectures.
