汇编语言实验报告.doc

实验报告一、实验目的汇编语言程序设计是计算机专业的重要的专业基础课，通过本综合性、设计性实验使学生进一步巩固课堂所学，全面熟悉、掌握8088宏汇编语言程序设计的基本方法和技巧，进一步提高编写程序、阅读分析程序及上机操作、调试程序的能力。二、实验要求编写一个程序，让红心和严在(0,0)到(140,140)的斜线上移动。时钟的常驻内存程序，要求：右上角显示时分秒。三、实验原理分析1、INT 10H 是一个中断向量，是由 BIOS 对屏幕及显示器所提供的服务程序。2、先在数据段定义好“心”的图形，代码段选定坐标，调用显示子程序显示在桌面上。3、将时间数值转换成ASCII码字符4、设置显示方式为40*25彩色文本方式开始5、MOV AH,2CH 取系统时间四、流程图退出时间显示？显示时间初始化屏幕 Y N初始化动画起点坐标、颜色显示图像是否到达终点 改变图像坐标 否 是结束五、源程序（加必要注释）和程序运行时的截屏STACK SEGMENT STACK DW 200 DUP (?)STACK ENDSDATA SEGMENT SPACE DB 1000 DUP ( ) PATTERN DB 24 DUP ( ),0C9H,8 DUP (0CDH),0BBH,6 DUP ( ) DB 24 DUP ( ),0BAH,8 DUP (20H),0BAH,6 DUP ( ) DB 24 DUP ( ),0C8H,8 DUP (0CDH),0BCH,6 DUP ( ) DBUFFER DB 8 DUP (:),12 DUP ( ) DBUFFER1 DB 20 DUP ( ) STR DB 0DH,0AH, INPUT Q TO QUIT!$ DELAY1 DW 0 ;延迟时间设置 DELAY2 DW 0 COLOUR DB 0 ;颜色设置 S_MOV DB 0 ;擦出或画图方式选择 LINE DW 0 ;行号 ROW DW 0 ;列号 PIX DB 0 ;颜色 XX DW 0 ;坐标（xx，yy） YY DW 0 ;
