Question

1) (5 points) Assuming a 64-bit address size, diagram out the bits used for tag, index and offset 2) (10 points) Given the reference stream in the table below, fill in the tag, index and offset and indicate which references are hits, misses and whatt of miss Reference Tag Index Offset Hit/Miss Type 0x00000014 0x001c0000 0x001c001c 0x00000018 0x00000010 Oxf01c0000 0x002c0000 0x003c0018 0x00000000 0x004c000c 0x001c0018 0x001c0000 3) 5 points) What Is the miss rate for this cache with this stream of references

Explanation / Answer

Solution:

Since the exact details of the cache is not provided here,

we are considering the below architecture for Tag, Index and Offset value.

1)

2)

3)

Total number of operations = 12

Number of misses = 7

Miss rate = 7/12 = 0.58333333333 = 58.33 %
