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 advanced challenges

Challenge 1 Hard

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.

Challenge 2 Hard

Design a comparison of two different cache architectures and analyze their performance regarding CPI reduction.

💡 Hint: Use empirical data and assumptions made during lectures.
