The main memory of a computer has 2 cm blocks while the cache has 2c blocks. If the cache uses the set associative mapping scheme with 2 blocks per set, then block k of the main memory maps to the set
Correct Answer: B
Question 33 Explanation:
No. of sets in cache = No. of blocks in cache/No. of blocks per set
= 2c/c
= c
∴ Cache set no. to which block k of main memory maps to
= (Main memory block no.) mod (Total set in cache)
= k mod c
= 2c/c
= c
∴ Cache set no. to which block k of main memory maps to
= (Main memory block no.) mod (Total set in cache)
= k mod c
(k mod m) of the cache
(k mod c) of the cache
(k mod 2c) of the cache
(k mod 2 cm) of the cache
