below is a list of 64-bit memory address references: 0xdf, 0xe7, 0x2c, 0xe7, 0xe2, 0x1e, 0x4c, 0xdf, 0xfa, 0xf0, 0x2d, 0xfe assume a direct mapped cache with 16 one-word blocks is used. for each of those references, identify the binary word address, the tag, the byte offset, and the index. also list whether each reference is a hit or a miss, assuming the cache is initially empty.
