其目的是：培养学生熟练掌握汇编语言指令系统，深化和巩固指令系统和编程方法，提高学生的编程应用能力。

为将来从事专业工作打下基础，培养良好的职业道德和严谨的工作作风。

二、课程设计的要求1)具备初步的独立分析和解决问题的能力；2)初步掌握问题分析、系统设计、程序编码、测试等基本方法和技能；3)提高综合运用所学的理论知识和方法的能力；4)训练用系统的观点和软件开发一般规进行软件开发，培养科学的工作方法和作风；5)设计的题目要求达到一定工作量，并具有一定的深度和难度；6)编写出课程设计说明书。

三、课程设计报告容（一）设计思路“我爱大自然”这个程序中包含了比较多的景物，既有静态的也有动态的，其中还有一段音乐。

为了节省存储空间，提高程序设计的效率和质量，使程序简洁、清晰，便于阅读，同时也为了便于修改和扩充，采用子程序设计技术和宏定义，根据程序要实现的若干主要功能及个功能块要调用的公共部分，将程序划分为若干个相对独立的模块，为每个模块编制独立的程序段，最后将这些子程序根据调用关系连成一个整体。

这样，整个程序就被分为几个子程序的有机统一。

根据BIOS中断调用原理，设置80×25彩色文本显示方式，分别编写一个子程序显示“I LOVE NATURE,LET US GO AIRING”和一个子程序在屏幕上“画”树。

这两个子程序所体现出来的事物都是的。

为了实现小鸟能在空中翩翩飞舞和小汽车在林荫路上行驶，还要调用擦除子程序和延时子程序。

擦除子程序的原理是根据相对位移设置光标位置，讲原来字符属性设置为黑底黑字，以达到擦除效果。

延时子程序的原理也很简单，即设置循环次数，让CPU做一些“无用功”，这样读者就能看到小鸟“飞起来”和小汽车“跑起来”。

可以改变循环次数来控制延时，达到想要的效果。

动态的事物就这样产生了。
