Question

Consider a processor that generates a 32-bit address and the system uses a direct-mapped cache. If the system has a cache size of 128 KB and each block is 8 words (1 word = 4 Bytes), then calculate: a. the number of bits for index, tag, and offset. b. the overhead (the number of extra bits stored in the cache other than data)

Step 1

To find the number of blocks, we divide the cache size by the block size: Number of blocks = Cache size / Block size Number of blocks = 128 KB / (8 words * 4 Bytes/word) Number of blocks = 128 KB / 32 Bytes Number of blocks = 4,096 blocks Show more…
