Consider a cache of 8 lines of 16 bytes each. Main memory is divided into blocks of 16 bytes each. That is, block 0 has bytes with addresses 0 through 15, and so on. Now consider a program that accesses memory in the following sequence of addresses: Loop three times: 10 through 20; 32 through 52. Once: 20 through 35. Suppose the cache is organized as direct mapped. Memory blocks 0, 8, 16 and so on are assigned to line...
