In a particular system it is observed that, the cache performance gets improved as a result of increasing the block size of the cache. The primary reason behind this is :
Helps improve miss rate b/c of principle of locality:
1)Temporal locality says that if something is accessed once, “it will probably be accessed again soon"
2)Spatial locality says that if something is accessed, something nearby it will probably be accessed
Note: Larger block sizes help with spatial locality. Easiest way to reduce miss rate is to increase cache block size
ANS OPTION D
Easiest way to reduce miss rate
but more miss overhead
option D is correct.
