Consider a direct-mapped cache with 32 blocks
Cache is initially empty, Block size = 16 bytes
The following memory addresses (in hexadecimal) are
referenced:
0x2B4, 0x2B8, 0x2BC, 0x3E8, 0x3EC,0x4F0, 0x8F4, 0x8F8, 0x8FC.

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...
