5. Below are some assumptions of memory access times: 1 memory bus clock cycle to send the address 10 memory bus clock cycles for each DRAM access initiated 1 memory bus clock cycle to send a word of data Based on these assumptions, please calculate the miss penalty of a four-word block for the following organizations of memory. (10%) (1) One-word-wide memory organization: the memory and the bus between the processor and the memory are both one word wide. (3%) (2) Wider memory organization: the memory and the bus between the processor and the memory are widened to two words. (3%) (3) Interleaved memory organization: the memory chips are organized in four banks, where each bank is one word wide, without widening the interconnection bus (in other words, the bus is still one word wide).
