97 中山資工 How many ,e,ory accesses are required to execute a "store" instruction with memory indirect addressing ? ans : 含IF則是3 不含則是2 (我算的結果都少1...) 95 清大電機 What is x if the maximum number of memory words you can use in a 32-bit MIPS machine in a single program is expressed as 2^x ? (Note:MIPS uses a byte addressing scheme.) ans : x = 26. 我是這樣想的 1 byte = 8 bit, 1 word = 4 byte x = 32 - lg(8) - lg(4) = 27 可是還是少1... 不知道我哪裡想錯了?? 先謝謝大家了~ -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 140.114.32.69
