These four operations, together with their options, use all 256 instruction codes . 這四種操作再加上對(duì)于它們的各種選擇方案,總共需要用掉全部256個(gè)指令代碼。
After every instruction fetch, if we increment this address, it will accurately point to the next instruction in the sequence . 在每次取指令后,如果我們使地址增量,那么就會(huì)準(zhǔn)確地指向指令代碼序列中的下一條指令。
The microprocessor instruction code must have some bits to identify every possible source register and destination register . 微處理機(jī)的指令代碼就必須要有若干位,以便能夠識(shí)別出每個(gè)可能的源寄存器和每個(gè)可能的目的地寄存器。
For an 8-bit micro-computer, all informationdata, characters, and instruction codesmust be stored in units of eight binary digits . 對(duì)一個(gè)八位的微計(jì)算機(jī)來說,所有的信息,其中包括數(shù)據(jù),字符和指令代碼等,都應(yīng)存入有八個(gè)二進(jìn)制數(shù)字的單元中。
