1/31武大微机原理实验报告汇总(4000字)微型计算机原理与接口技术实验报告【实验名称】汇编语言程序的编辑与调试【实验目的】学习汇编源程序的编辑、编译、链接、执行全过程。学习编辑文件、TASM、TLINK的使用方法以及汇编语言的语法规则。学习使用TD对程序进行调试的方法。【实验步骤】1、将程序1输入并存储为文件2、编译与链接首先对源代码进行编译，指令为：C：TASMHELLO/zi生成编译如果报错，需要回到编辑窗口修改源代码，存盘后重新编译编译成功后，链接生成可执行文件C：TLINKHELLO/v/3生成3、启动调试工具TD键入：C：TDHELLO成功启动TD之后，TD进入MODULE显示模式，屏幕上显示HELLO-ASM源程序，一个三角形符号指示出了标号为BEG的那条指令是启动指令。4、动态调2/31试连续执行程序按F9键。要求：上述实验中的各变量单元要在数据区定义；用TD调试，运行并修改各变量的值，观察结果存放单元。【程序框图】【实验1】【实验2】【程序代码】【实验1】DATASEGMENTADB40BDB50SDB?DATAENDSCODESEGMENTASSUMECS:CODE,DS:DATABEG:MOVAX,DATAMOVDS,AXMOVBL,AADDBL,BMOVBH,0ADCBH,0MOVAL,AANDAL,BMOVCL,2MULCLSUBBX,AXMOVS,BXMOVAH,4CHINT21HCODEENDSENDBEG【实验2】DATASEGMENTADB?BDB?CDB?VOLUMEDD?DATAENDS3/31CODESEGMENTASSUMECS:CODE,DS:DATABEG:MOVAX,DATAMOVDS,AXMOVAH,1INT21HSUBAL,30HMOVA,ALMOVAH,1INT21HSUBAL,30HMOVB,ALMOVAH,1INT21HSUBAL,30HMOVC,ALMOVBL,BMULBLMOVBL,AMOVBH,0MULBXMOVWORDPTRVOLUME,AXMOVWORDPTRVOLUME+2,DXMOVAH,4CHINT21HCODEENDSENDBEG【实验结果】【实验1】：程序运行后，运行结果S=26H,与预期相符。所有通用寄存器即段寄存器的值如下：AX=1B6FBX=000FCX=0206DX=3002DS=04BACS=0000【实验2】：程序运行时，取a=4，b=5，c=6，运行后，VOLUME=120，与预期相符所有通用寄存器即段寄存器的值如下：AX=1B6FBX=000FCX=0206DX=3002DS=04BACS=0000【实验名称】循环实验的设计【实验目的】学习并掌握循环程序的设计方4/31法。【实验内容】【实验1】用表格形式显示ASCII字符。实验要求：按15行16列的表格形式显示ASCII码为10H-100H的所有字符，即以行为主的顺序及ASCII码递增的次序依次显示对应的字符。每16个字符为一行，每行中的相邻两个字符之间用空白符隔开。提示：显示每个字符可使用功能号为02的显示输出功能调用，使用方法如下：movah,02hmovdl,输出字符的ASCII码int21h本题中可把DI初始化为10H，然后不断使其加1以取得下一个字符时ASCII码。显示空白符时，用其ASCII码0置入DI寄存器。每行结束时，用显示回车和换行符来结束本行并开始下一行。由于逐个显示相继的ASCII字符时，需要保存并不断修改dl寄存器的内容，而显示空白、回车、换行符时也需要使用DI寄存器，为此可使用堆找来保存相继的ASCII字符。具体用法是：在显示空白或回车、换行符前用指令pushdx5/31把DI的内容保存到堆栈中去。在显示空白或回车、换行符后用指令popdx恢复DI寄存器的原始内容。【实验2】编程计算：S=1+2+3+N100的最大项数N以及对应的和S。实验要求：将最大项数与和数分别存入N和SUM单元，用TD调试，运行程序并检查结果；将结果在屏幕上以16进制数显示。显示格式：MAXN=HSUM=H。【程序框图】【实验1】【实验2】【实验1】【程序代码】CODESEGMENTMAINPROCFARASSUMECS:CODEBEG:MOVAH,02HMOVDL,10H;设置初始输出为ASCII的10hMOVBL,15;输出显示为15行E:6/31MOVCX,16;设置循环次数，16，表示输出显示为16列l:INT21H;显示输出PUSHDX;推入堆栈MOVAH,02HMOVDL,0INT21HMOVAH,02HMOVDL,0INT21H;显示空白符POPDX;将栈顶元素推出INCDL;设置下一个元素LOOPl;循环输出每行的16个ASCII元素PUSHDX;将下一行的首元素推入堆栈MOVAH,02HMOVDL,0DHINT21HMOVAH,02HMOVDL,0AHINT21H;输出换行POPDX;将栈顶元素推出DECBLCMPBL,0;比较确定是否已经输出15行元素JNEE;若还未完成输出，则跳转至e，继续进行下一行元素的输出JEEXIT;否则退出程序EXIT:MOVAX,4C00HINT21HMAINENDPCODEENDSENDBEG【实验2】7/31DATASEGMENTNDB?;开辟一个字节单元SUMDB?MESG1DBMAXN=,$MESG2DBSUM=,$DATAENDSCODESEGMENTASSUMECS:CODE,DS:DATA;段分配BEG:MOVAX,DATA;段基址DSMOVDS,AXMOVMOVL1:INCADDCMPJBESUBMOVMOVMOVMOVINTMOVANDRORCMPJLADDNEXT:ADDMOVMOVINTMOVANDCMPJLADDNEXT1:ADDOVMOVINTMOVINTMOVMOVBL,0H;给BL和AL赋初始值0AL,0HBLAL,BLAL,64HL1;无符号数AL,BL;所得AL大于100，故要减去BLN,BL;最大项数N单元SUM,AL;和数SUM单元AH,9;9号功能调用，输出字符串DX,OFFSETMESG121HAL,N;2号功能调用，输出两个空格AL,0F0H;屏蔽低四位AL,4;右移4位AL,10;与10比较NEXT;小于跳转NEXTAL,7;否则加7AL,30H8/31AH,02HDL,AL21HAL,NAL,0FH;屏蔽高4位AL,10NEXT1AL,7AL,30HAH,02HDL,AL21HDL,H;显示出H21HAH,02HDL,0DHINT21H;回车MOVAH,02HMOVDL,0AHINT21H;换行MOVAH,9;9号功能调用，输出字符串MOVDX,OFFSETMESG2INT21HANDAL,0F0H;屏蔽低四位RORAL,4;右移4位CMPAL,10JLNEXT2ADDAL,7NEXT2:ADDAL,30HMOVAH,02HMOVDL,ALINT21HMOVAL,SUMANDAL,0FHJLNEXT3ADDAL,7NEXT3:ADDAL,30HMOVAH,02HMOVDL,ALINT21HMOVDL,HINT21HMOVAH,4CHINT21HCODEENDSENDBEG【实验1】9/31实验一运行后显示结果为;与10比较;小于跳转NEXT;否则加7;屏蔽高4位;显示出H;返回DOS操作系统【调试结果】与预期相符【实验2】实验二运行后结果为“MAX=0DHSUM=5BH”，与预期相符。【实验名称】分支程序设计【实验目的】学习分支程序的结构，掌握具有分支结构程序的设计方法。【实验内容】【实验1】分类统计字符个数COUNT_CHAR。【实验2】显示月份名direct。试编写一程序，根据用户键入的月份数在屏上显示该月份的英文缩写名【程序代码及框图】【实验1】DATASEGMENTSTRINGLABELBYTEMAXDB80ACTDB?STOKNDB80DUPDIGITDB0LETTERDB0OTHERDB0MESS1DBPLEASEINPUT10/31CHARS:,0DH,0AH,$MESS2DB0DH,0AH,$MESS3DBDIGIT:,0H,$MESS4DBLETTER:,0H,$MESS5DBOTHER:,0H,$MESS6DBH,0DH,0AH,$NDB3DATAENDSCODESEGMENTASSUMECS:CODE,DS:DATACOUNT_CHARPROCFARPUSHDSSUBAX,AXPUSHAXMOVAX,DATAMOVDS,AXLEADX,MESS1MOVAH,09INT21HLEADX,STRINGMOVAH,0AHINT21HLEADX,MESS2MOVAH,09HINT21HLEASI,STOKNSUBCH,CHMOVCL,ACTAGAIN:MOVAL,SICMPAL,30HJLOTHER1CMPAL,3AHJLDIGIT1CMPAL,41HJLOTHER1CMPAL,5BHJLLETTER1CMPAL,61HJLOTHER1CMP11/31AL,7BHJLLETTER1OTHER1:INCOTHERINCSILOOPAGAINJMPPRINTDIGIT1:INCDIGITINCSILOOPAGAINJMPPRINTLETTER1:INCLETTERINCSILOOPAGAINPRINT:MOVCH,2MOVBL,DIGITLEADX,MESS3MOVAH,09INT21HROTATE:MOVCL,4ROLBL,CLMOVAL,BLANDAL,0FHADDAL,30HCMPAL,3AHJLPRINT1ADDAL,7HPRINT1:MOVDL,ALMOVAH,2INT21HDECCHJNZROTATELEADX,MESS6MOVAH,09INT21HDECNCMPN,2JZLETTER2CMPN,1JZOTHER2JMPEXITLETTER2:LEADX,MESS4MOVAH,09INT21HMOVCH,2MOVBL,LETTERJMPROTATEOTHER2:LEADX,MESS5MOVAH,09INT21HMOVCH,212/31MOVBL,OTHERJMPROTATEEXIT:RETCOUNT_CHARENDPCODEENDSENDCOUNT_CHAR【实验2】DATASEGMENTMESG1DBPLEASEINPUTTHENUMBERFORMONTH,0DH,0AH,$MESG2DBERROR!,0DH,0AH,$NUMDB3COUNTDB?STOREDB2DUPMONTABDBJAN,FEB,MAR,APR,MAY,JUNDBJUL,AUG,SEP,OCT,NOV,DECMONTHDB3DUP,0DH,0AH,$DATAENDSCODESEGMENTASSUMECS:CODE,DS:DATASTART:MOVAX,DATAMOVDS,AXMOVES,AXMOVDX,OFFSETMESG1MOVAH,09HINT21HMOVDX,OFFSETNUMMOVAH,0AHINT21H13/31CMPCOUNT,0JZEXITCMPCOUNT,2JZNEXTMOVAL,STOREXORAL,30HMOVAH,0JMPGOONNEXT:MOVAH,STOREMOVAL,STORE+1XORAX,3030HCMPAH,0JZGOONCMPAH,1JNZLASTSUBAH,AHADDAL,10GOON:CMPAL,0JZLASTCMPAL,12JALASTDECALMOVBL,3MULBLLEASI,MONTABADDSI,AXLEADI,MONTHMOVCX,3CLDREPMOVSBDISP:MOVDX,OFFSETMONTHMOVAH,09HINT21HJMPSTARTLAST:MOVDX,OFFSETMESG2MOVAH,09HINT21HJMPSTARTEXIT:MOVAH,4CHINT21H14/31CODEENDSENDSTART【实验结果】
