Below is a list of memory address references: 0x03, 0xb3, 0x03, 0x03, 0xbf, 0xcf, 0xbe, 0x0e, 0x05, 0x25, 0x0f, 0x0e For each of these references, identify the binary word address, the tag, and the index given a direct-mapped cache with 16 one-word blocks (thus lower 4 bits are index and we have 32-bit data). Also list whether each reference is a hit or a miss, assuming the cache is initially empty. Ignore byte offset bits for simplicity. For each of these references, identify the binary word address, the tag, the index, and the offset given a direct-mapped cache with two-word blocks (32*2=64-bit data) and a total size of eight blocks. Also list if each reference is a hit or a miss, assuming the cache is initially empty. Consider one bit for word offset and ignore byte offset bits for simplicity.

Question
  1. Below is a list of memory address references:

0x03, 0xb3, 0x03, 0x03, 0xbf, 0xcf, 0xbe, 0x0e, 0x05, 0x25, 0x0f, 0x0e

  • For each of these references, identify the binary word address, the tag, and the index given a direct-mapped cache with 16 one-word blocks (thus lower 4 bits are index and we have 32-bit data). Also list whether each reference is a hit or a miss, assuming the cache is initially empty. Ignore byte offset bits for simplicity.
