Caches are important to providing a high performance memory hierarchy to processors. Below is a list of 32-bit memory address references, given as word addresses. 6, 214, 175, 149, 214, 6 Given a direct-mapped cache with four-word blocks and a total size of 16 blocks. Please fill in the following table. You may assume that the cache is initially empty. Because the given address is word address, we may compute tags and indices based on word address. Four-word blocks indicate the right most 2 bits are offset in a block. 16 blocks indicates there are 4 bits for indices, and the rest 26 bits will be the tag.

Expert Solution

We have to use direct mapped caching and create a table

Every address will be represented in 32 bit binary notation

Word offset is represented by the right most bits of the binary memory address and will be in italic

Index bits will be the next 4 bits of the binary memory address and will be in bold

Tag bits will be remaining 26 bits and they will be represented without any formatting.

The cache is initially empty

The first address is 6 and is placed in block 1 and the result will be a miss.

The second address is 214 and is placed in block 5 and the result will be a miss.

The third address is 175 and is placed in block 11 and the result will be a miss.

The fourth address is 149 and is placed in block 5 replacing the its previous contents and the result will be a miss.

The fifth address is 214 and is placed in block 5 replacing the its previous contents and the result will be a miss.

The sixth address is 6 but it is already present in block 1, so this memory access will be a hit

Word Address (Binary)	Tag (Hex)	Index (Hex)	Hit / Miss
6 (00000000000000000000000000000110)	0x0000000	0x1	Miss
214 (00000000000000000000000011010110)	0x0000003	0x5	Miss
175 (00000000000000000000000010101111)	0x0000002	0xb	Miss
149 (00000000000000000000000010010101)	0x0000002	0x5	Miss
214 (00000000000000000000000011010110)	0x0000003	0x5	Miss
6 (00000000000000000000000000000110)	0x0000000	0x1	Hit
