操作系統(tǒng)課程實(shí)驗(yàn)報(bào)告

《操作系統(tǒng)》實(shí)驗(yàn)報(bào)告學(xué)號： 度與內(nèi)存管理方法。幫助了解在不同的存儲管理方式下，應(yīng)怎樣實(shí)現(xiàn)主存空間的分配和回收。二、實(shí)驗(yàn)要求2、從就緒隊(duì)首選進(jìn)程運(yùn)行：優(yōu)先權(quán)-1/要求運(yùn)行時(shí)間-1要求運(yùn)行時(shí)間=0時(shí)，撤銷該進(jìn)程5、規(guī)定道數(shù)，設(shè)置后備隊(duì)列和掛起狀態(tài)。若內(nèi)存中進(jìn)程少于規(guī)定道數(shù)，可自動從后備隊(duì)列調(diào)度一作業(yè)進(jìn)入。被掛起進(jìn)程入掛起隊(duì)列，設(shè)置解掛功能用于將指定掛起進(jìn)程解掛入就緒隊(duì)列。表目內(nèi)容：起址、長度、狀態(tài)(未分/空表目)PCB指針}10、進(jìn)程完成后，回收主存，并與相鄰空閑分區(qū)合并。 三、實(shí)驗(yàn)內(nèi)容選擇一個調(diào)度算法，實(shí)現(xiàn)處理機(jī)調(diào)度。3、主存儲器空間的分配和回收。在可變分區(qū)管理方式下，采用最先適應(yīng)算法實(shí)現(xiàn)主存四、實(shí)驗(yàn)原理該模擬系統(tǒng)采用java語言實(shí)現(xiàn)，要實(shí)現(xiàn)的功能有新建進(jìn)程、進(jìn)程調(diào)度、掛起進(jìn)程、解waitingsuspend列中的進(jìn)程的狀態(tài)為new。CPU每次調(diào)度時(shí)都從就緒隊(duì)列中取進(jìn)程，在進(jìn)程執(zhí)行過程中如果下一個操作時(shí)IO操作，則將進(jìn)程插入到waiting隊(duì)列。在系統(tǒng)運(yùn)行過程中可以執(zhí)行進(jìn)程中的進(jìn)程從原來的隊(duì)列中刪除并插入到掛起隊(duì)列。進(jìn)行解掛操作時(shí)將選中的進(jìn)程從掛起隊(duì)列中刪除并插入該進(jìn)程原來所處的隊(duì)列。插入時(shí)根據(jù)該進(jìn)程的優(yōu)先權(quán)插入到隊(duì)列中的合適位置，插入后保持隊(duì)列按優(yōu)先權(quán)從大到小排最高。當(dāng)選擇按時(shí)間片輪轉(zhuǎn)調(diào)度時(shí)，所有隊(duì)列都采用先進(jìn)先出隊(duì)列，先進(jìn)先出隊(duì)列采用一個實(shí)現(xiàn)了先進(jìn)先出。 ?內(nèi)存管理該實(shí)驗(yàn)基于實(shí)驗(yàn)一完成，核心是內(nèi)存的分配和回收，在實(shí)驗(yàn)一的基礎(chǔ)上增加內(nèi)存管理部分，在新建進(jìn)程的時(shí)候增加一個輸入內(nèi)存大小的輸入框，在進(jìn)程進(jìn)入內(nèi)存時(shí)要分配內(nèi)存，間大小以及空間使用狀態(tài)。初始時(shí)只有一個空間，當(dāng)CPU啟動時(shí)要分配內(nèi)存，內(nèi)存分配采用最先適應(yīng)算法?；厥諆?nèi)存時(shí)如果有相鄰空閑空間，則要進(jìn)行空閑空間合并。}}1.divDTO：publicclass{privateprivateprivatedivDTOintdivBase;intlength;intdivFlag;publicdivDTO(intdivBase,intlength,intdivFlag){this.divBase=divBase;this.divFlag=divFlag;this.length=length;}publicdivDTO(){}publicvoidsetDivBase(intbase){this.divBase=base;}publicintgetDivBase(){returnthis.divBase;}publicvoidsetLength(intlength){this.length=length;}；publicintgetLength(){returnthis.length;}publicvoidsetDivFlag(intflag){this.divFlag=flag;}publicintgetDivFalg(){returnthis.divFlag;}}2.PcbDTO：publicclassPcbDTO{staticfinalintRunning=1;staticfinalintReady=2;staticfinalintWaiting=3;privateStringprocessName;privateintrunTime;privateintprority;privateintprocessState;privateintbase;privateintlimit;privateintpcbFlag;publicPcbDTO(Stringname,inttime,intpro,intbase,intlimit){cessName=name;this.runTime=time;rity=pro;cessState=0;this.limit=limit;this.base=base;}publicPcbDTO(){this.pcbFlag=0;}publicvoidsetProcessName(Stringname){cessName=name;}；publicStringgetProcessName(){returnprocessName;}publicvoidsetRunTime(inttime){this.runTime=time;}publicintgetRunTime(){returnthis.runTime;}publicvoidsetPrority(intprority){rity=prority;}publicintgetPrority(){returnrity;}publicvoidsetProcessState(intstate){cessState=state;}publicStringgetProcessState(){Strings=newString();if(cessState==1){s="running";}elseif(cessState==2){s="ready";}elseif(cessState==3){s="waiting";}returns;}
