A certain processor deploys a single-level cache. The cache block size is 8 words and the word size is 4 bytes. The memory system uses a 60-MHz clock. To service a cache miss, the memory controller first takes 1 cycle to accept the starting address of the block, it then takes 3 cycles to fetch all the eight words of the block, and finally transmits the words of the requested block at the rate of 1 word per cycle. The maximum bandwidth for the memory system when the program running on the processor issues a series of read operations is _____  ×  106 bytes/sec.
    Correct answer is '160'. Can you explain this answer?

    A certain processor deploys a single-level cache. The cache block size...
    To accept the starting address = 1 cycle
    To fetch all eight words – 3 cycles
    To transmits the words of the requested block at the rate of 1 word per cycle- 8cycles
    Total 12 cycles required 

    Bandwidth is =160 * 106 bytes/sec

    To calculate the maximum bandwidth of the memory system, we need to calculate the number of cycles required to service a cache miss and the total number of words transferred.

    The cache block size is 8 words, and each word is 4 bytes. So, the total number of bytes in a cache block is:
    8 words * 4 bytes/word = 32 bytes

    The memory controller takes 3 cycles to fetch all the eight words of the block. Since the clock frequency is 60 MHz, each cycle takes 1/60 MHz = 16.67 ns.

    Therefore, the time taken to fetch all the words of a block is:
    3 cycles * 16.67 ns/cycle = 50 ns

    The memory controller transmits the words of the requested block at the rate of 1 word per cycle. So, the total number of cycles required to transmit all the words of a block is 8 cycles.

    The total number of cycles required to service a cache miss is the sum of the cycles for accepting the starting address, fetching the words, and transmitting the words:
    1 cycle (accepting address) + 3 cycles (fetching words) + 8 cycles (transmitting words) = 12 cycles

    The maximum bandwidth of the memory system is the total number of words transferred per second. Since each block has 8 words, the total number of blocks transferred per second is:
    60 MHz / 12 cycles/block = 5 million blocks/second

    The total number of words transferred per second is the product of the total number of blocks and the number of words per block:
    5 million blocks/second * 8 words/block = 40 million words/second

    Therefore, the maximum bandwidth for the memory system is 40 million words/second.
