WebAug 20, 2024 · Data access is performed by processor in blocks of small size called cache lines, so cache actually consists of many cache lines. The size of one cache line is 64 bytes. At least one cache line is copied from the memory to cache, if we try to read any data from memory. An access to any byte of data from the same cache line will be fast. WebSince 32 bytes/line and size of cache line = size of main memory block, this means block offset = 5 bits. Hence remaining 31 bits is block number ( = tag + index). number of cache lines = 128KB/32B, therefore, 12 bits for index and hence remaining 19 bits for tag. 2. Physical address = 36 bits.
