Cache line or block size = 64 byte -> Block Offset = log 64 = 6 bits
Total # of block inside cache = 512/64 = 8
Therefore total # of set = 8/2= 4
Therefore index bits = log 4 = 2 bits
# of tag bits = 32 -(6+2) = 32-8=24 bits

Tag (24 bits) |
Set Index (2 bits) |
Block Offset (6 bits) |

) Consider an 8-way associative 64 Kilo Byte cache with 32 byte cache lines. Assume memory addresses are 32 bits long. a). Show how a 32-bit address is used to access the cache (show how many bits for Tag, Index and Byte offset). b). Calculate the total number of bits needed for this cache including tag bits, valid bits and data c). Translate the following addresses (in hex) to cache set number, byte number and tag (i) B2FE3053hex (ii) FFFFA04Ehex...
Given a 32-bit address, calculate the following values for a two-way set associative for: Cache size: 32KB Block size: 64B i) The number of bits in the block offset field. ii) The number of index bits. iii) The number of sets in the cache. iv) The number of tag bits.
A 256kiB (2^18 bytes) cache has a block size of 32 bytes and is 32-way set-associative. How many bits of a 32-bit address will be in the Tag, Index, and Bock Offset?
Q2. Consider a four-way set associative cache with a data size of 64 KB. The CPU generates a 32-bit byte addressable memory address. Each memory word contains 4 bytes. The block size is 16 bytes. Show the logical partitioning of the memory address into byte offset, cache index, and tag components.
A primary memory system consists of 128 address bits. Each block within the cache is 256 bytes. The total cache size is 131,072 bytes. What are the sizes of the tag and index in the cache? First, find the number of blocks. 128,000 bytes # Blocks = 256 bytes per block bort = 512 blocks Where does the 128,000 come from?? Now find the number of bits required to distinguish all the blocks. This is the index aka set size....

0. (10 Points) A four-core i7 has a 8 MB L3 cache 8-way set associative of block size 32 bytes. It uses 30-bit block address (36-bit physical address, 6-bit block offset). What is the addressing organization of L3? ANSWER Block Address - Block offset Index Tag-
Cache Layout: A processor has a separate D-cache and an I-cache. D-cache: 64KB, 4-way set associative, block size of 1 word, write-back policy I-cache: 32KB, direct mapped cache, block size of 1 word The processor uses the LRU algorithm for its replacement policy. Answer the following questions. Make sure that you account for all the book -keeping bits. A word is 4 bytes (a) Calculate the number of tag, index and offset bits for the D-cache. (b) Calculate the number...
