Consider a cache memory with blocks of 23 = words (1 word = 4 bytes) , with a bus Main Memory - Cache of 32 bits, and with 1 clock cycle to send the address, a row cycle time (DRAM) of 17 cycles (5 less clock cycles for the column access time) and 1 clock cycle to return a word. Assuming that each word is in a different DRAM row, calculate the bandwidth of the system in byte per clock cycles (bandwidth = number of bytes per clock cycles) for the transfer of one block from Main Memory to Cache Memory (not interleaved memory system). Provide the solution with at least 2 decimals
