Question
A major advantage of direct mapped cache is its simplicity and ease of implementation. The main disadvantage of direct mapped cache is:
it is more expensive than fully associative and set associative mapping
it has a greater access time than any other method
its performance is degraded if two or more blocks that map to the same location are used alternately
it does not allow the cache to store the tag that corresponds to the block currently residing in that cache location
A.it is more expensive than fully associative and set associative mapping
B.it has a greater access time than any other method
C.its performance is degraded if two or more blocks that map to the same location are used alternately
D.it does not allow the cache to store the tag that corresponds to the block currently residing in that cache location
Explanation / Answer
Answer (C)
its performance is degraded if two or more blocks that map to the same location are used alternately
reasoning: because of continuous swapping made at the same locations, when referencing is made at the same location
