總匯編語(yǔ)言計(jì)算器課程設(shè)計(jì)

1、實(shí)用標(biāo)準(zhǔn)文案1.設(shè)計(jì)目標(biāo)運(yùn)用匯編語(yǔ)言,制作一個(gè)計(jì)算的程序,實(shí)現(xiàn)簡(jiǎn)單計(jì)算器的一般功能,能夠在DO以面下進(jìn)行簡(jiǎn)單的加、減、乘、除的簡(jiǎn)單計(jì)算.程序應(yīng)有操作提示、輸入和輸出.自動(dòng)閃爍光標(biāo),并提示輸入信息.輸入正確的數(shù)值等符號(hào)后可以進(jìn)行正確的運(yùn)算,程序計(jì)算其結(jié)果值并輸出.程序無(wú)需查錯(cuò)功能,所輸入的都是正確的四那么運(yùn)算表達(dá)式,并且表達(dá)式中運(yùn)算分量均為無(wú)正負(fù)號(hào)整數(shù),運(yùn)算符為+、-、*、/,最后結(jié)果以十進(jìn)制數(shù)表示.且程序主界面需為一個(gè)由組成邊框的矩形窗口.匯編語(yǔ)言直接同計(jì)算機(jī)的底層軟件甚至硬件進(jìn)行交互,它具有如下一些優(yōu)點(diǎn)：能夠直接訪問(wèn)與硬件相關(guān)的存儲(chǔ)器或I/O端口； 能夠不受編譯器的限制,對(duì)生成的二進(jìn)制代碼進(jìn)

2、行完全的限制； 能夠?qū)﹃P(guān)鍵代碼進(jìn)行更準(zhǔn)確的限制；能夠根據(jù)特定的應(yīng)用對(duì)代碼做最正確的優(yōu)化,提升運(yùn)行速度；能夠最大限度地發(fā)揮硬件的功能.2 .軟件設(shè)計(jì)2.1程序設(shè)計(jì)的根本思想主模塊： 首先提供一個(gè)主界面,提示用戶按要求輸入具體的數(shù)據(jù)和所要進(jìn)行的操作,輸入完畢后給出結(jié)果.如果輸入過(guò)程中發(fā)現(xiàn)非法輸入,那么立即給與提示,程序自動(dòng)刷新界面,提示繼續(xù)輸入.計(jì)算顯示完畢后,按提示選擇是否要繼續(xù)計(jì)算,不選擇繼續(xù)那么結(jié)束.對(duì)屏幕上輸入字符串的接受,為INPUT語(yǔ)句段,見(jiàn)源代碼,主要是將數(shù)字和運(yùn)算符分開(kāi)存放.MATCFF程序,子程序內(nèi)有三次跳轉(zhuǎn),將運(yùn)算符選擇正確的語(yǔ)句進(jìn)行計(jì)算.由于操作符只有+、-、*、/,沒(méi)有涉及

3、到括號(hào),不用考慮括號(hào)的匹配問(wèn)題.流程圖如下:圖1主模塊流程圖子模塊： 完成對(duì)數(shù)據(jù)的進(jìn)一步加工處理,轉(zhuǎn)換格式并得出結(jié)果.首先根據(jù)輸入調(diào)用對(duì)應(yīng)的“+、-、“*、“/四個(gè)函數(shù)模塊,這是本程序的核心模塊,其他局部的一些小模塊都是為這幾個(gè)模塊效勞的,大致的流程圖如下列圖2:精彩文檔實(shí)用標(biāo)準(zhǔn)文案調(diào)用對(duì)應(yīng)模塊運(yùn)算數(shù)據(jù),得出結(jié)果圖2子模塊流程圖2.2代碼STACKSEGMENTSTACKDB200DUP(0)STACKENDSDATASEGMENTOPSDBOPDDBOPERDBTITDB*1,0DH,0AHDB*MadeBy*,0DH,0AH;0DHDB*TongXinJiSuanQiXiaoZu*,0DH
