3 cards from this section. Quick, good the night before a test.
What is the main advantage of a Fully Associative Cache over a Direct Mapped Cache?
Think about conflict situations in cache placements.
Define a Cache Miss.
Recall what happens when data needs to be fetched from the main memory.
Which cache architecture allows a memory block to be placed in any cache line?
This type of cache minimizes conflicts.
True or False: In a Direct Mapped Cache, each memory block can be placed in multiple locations in the cache.
Consider how mapping works.
Design a small system with a 4-line cache where you need to analyze the performance of accesses: 0, 1, 2, 3, 1, 2, 4 using a direct mapped chassis. Include potential misses and hits as blocks are accessed.
Pattern your approach by writing down the state of the cache after each access.
Compare the performance of a 2-way set associative cache versus a fully associative cache with 4 lines when accessing blocks: 0, 1, 2, 0, 1. Document hits and misses.
Break down by analyzing what’s stored over each step for both cache types.
