Question 1

What occurs during a cache miss?

  • The data is found in the cache
  • Data needs to be fetched from the main memory
  • Cache is flushed

💡 Hint: Recall what happens when the cache does not have the data you want.

Question 2

True or False: In a fully associative cache, any memory block can be placed in any line.

Challenge Problems

Push your limits with challenges.

Question 1

Given a cache with 32 lines that is 4-way set associative, determine how many sets are present and explain the significance of this structure for reducing cache misses.

💡 Hint: Think about how flexibility in placing blocks can minimize misses.

Question 2

Describe a scenario where a direct-mapped cache might lead to a higher miss rate compared to a 4-way set associative cache.

💡 Hint: Consider how the mapping process could result in lost data in one structure but not in another.
