5. Consider two microprocessors having 8- and 16-bit-wide external data buses, respectively. The two processors are identical otherwise and their bus cycles take just as long. (a) Suppose all instructions and operands are one byte long, by what factor do the maximum data transfer rates differ?
I have a little bit problem with my late quiz for computer architecture, I get the answer from my lecturer but I still don't feel fully understand, can I ask for some help: In a computer system, the memory has 32 blocks and the cache has 8 blocks. Assume there is only one word per block with 4 bytes in one word. The reference sequence in terms of word location is 0, 2, 4, 10, 5, 12, 8, 18, 13. If the cache is direct-mapped, how many misses do we have if the cache is initially empty? Can you give the hit or miss for each reference?
