Consider a 2-way set associative cache memory with 4 sets and total 8 cache blocks (0-7) and a main memory with 128 blocks (0-127). What memory blocks will be present in the cache after the following sequence of memory block references if LRU policy is used for cache block replacement. Assuming that initially the cache did not have any memory block from the current job?
0 5 3 9 7 0 16 55
Correct Answer: C
Question 13 Explanation:
The cache is 2-way associative, so in a set, there can be 2 block present at a time.
So,
Since, each set has only 2 places, 3 will be thrown out as its the least recently used block. So final content of cache will be
0 5 7 9 16 55
Hence, answer is (C).
