Question 1

What is the primary function of cache memory?

  • To store rarely used data
  • To enhance access speed to frequently accessed data
  • To eliminate the need for RAM

πŸ’‘ Hint: Focus on the role cache plays in relation to the CPU.

Question 2

True or False: A higher hit rate indicates a better performing cache.

  • True
  • False

πŸ’‘ Hint: Think about the efficiency of data retrieval.

Challenge Problems

Push your limits with challenges.

Question 1

Suppose you have a system with a cache that achieves a 90% hit rate. If the average memory access time is 10 ns for hits and 50 ns for misses, what is the average memory access time?

πŸ’‘ Hint: Be careful to calculate the hit and miss percentages correctly!

Question 2

Evaluate how changing a write policy from write-back to write-through may impact system performance, especially in a heavily loaded server environment.

πŸ’‘ Hint: Consider trade-offs between consistency and performance.
