WebTherefore, the total cache size is 64*16 = 1024 bytes. Since the memory address is 16 bits, it can address 2^16 memory locations. Each memory location is a byte, so the total memory size is 2^16 bytes = 64 KB. To determine the tag and index bits for the cache, we need to divide the memory address into three parts: tag, index, and byte offset. daily sayings of love
