【摘要】 为了使学生更好地理解并掌握BIOS功能调用与程序设计,达到良好的教学效果。利用BIOS中断功能调用指令,采用汇编语言编程,在Emu8086汇编语言开发软件下,借助字模提取软件,结合显示器字符、图形显示原理,将屏幕划分成二维坐标系统,设计开发出一款软件,实现显示器屏幕字符、图案的显示功能。实验结果证明,通过计算机设计与仿真,学生能够做到举一反三,在原有基础上设计开发出各种漂亮的图案和字样,牢固掌握了BIOS功能调用功能及编程方法。在此将电脑屏幕简化成二维坐标系统,结合字模提取软件后,相对于传统的屏幕点阵系统,编程难度大大降低了。更多还原

【Abstract】 In order to make students understand and master the BIOS function calls better,and achieve good teaching effect,a software was designed to realize display functions of screen characters and patterns by using assembly language programming,matrix extraction software,display principle of character and graphics on the computer screen,and by dividing the computer screen into a two-dimensional coordinate system in Emu8086 assembly language development environment.Experimental results show that the students can master knowledge points very well through the design and simulation by computer.The innovation in this article is that the computer screen is simplified into a two-dimensional coordinate system,which can greatly reduce the programming difficulty bymeans of matrix extraction software,relative to traditional screen dot system.更多还原
