3 cards from this section. Quick, good the night before a test.
What is a direct mapped cache?
Think about how memory blocks are stored.
What does cache miss mean?
Recall what happens when the data isn't available.
What determines the set location in a set associative cache?
Review the formula we discussed.
True or False: In a fully associative cache, a block can only go into one specific cache line.
Think about the flexibility of placements.
You are given a cache with 16 lines configured as an 8-way set associative cache. Calculate the number of sets and explain how you would access data.
Focus on how you can use both the total lines and ways to find sets.
If a sequence of 10 memory accesses from blocks numbered 0 through 9 are run on a direct-mapped cache of 4 lines, outline the expected cache miss pattern.
Think about how the mapping affects repeated accesses.
