Set - Associative and direct mapping

What is the primary advantage of set associative mapping over direct mapping in cache design?

• Higher associativity

• Lower cache size

• Faster access time

• Lower miss rate

In set associative mapping, how is the cache divided?

• Into equal-sized blocks

• Into sets, each containing multiple lines

• Into single lines

• Into cache and main memory

What does the term "associativity" refer to in set associative mapping?

• The size of the cache

• The number of lines in each set

• The relationship between cache and main memory

• The degree to which a line can be placed in multiple sets

How does set associative mapping help reduce cache conflicts compared to direct mapping?

• By increasing cache size

• By allowing multiple lines to map to the same set

• By decreasing cache associativity

• By using a smaller block size

What is a disadvantage of set associative mapping?

• Higher miss rate

• Lower cache capacity

• Slower access time

• Limited flexibility in mapping

In a 2-way set associative mapping, how many sets are there?

• 1

• 2

• 4

• 8

Which of the following is a common replacement policy in set associative mapping?

• First-In-First-Out (FIFO)

• Least Recently Used (LRU)

• Random replacement

• All of the above

What happens if a line is not found in any set in set associative mapping?

• A cache hit occurs

• A cache conflict occurs

• A cache miss occurs

• A cache replacement occurs

Which parameter determines the associativity level in set associative mapping?

• Block size

• Cache size

• Number of sets

• Cache access time

In set associative mapping, what is the advantage of a higher associativity level?

• Smaller cache size

• Lower cache cost

• Reduced cache conflicts

• Faster access time
