摘要
为满足目前高集成度嵌入式平台下对功能性要求日益复杂和开发周期进一步缩短的需求,以ARM9处理器EP9315构建的平台为实例,介绍了一种VxWorks实时嵌入式操作系统下标准多媒体开发库WindML的显示驱动开发方法和要点。描述了从驱动的安装介入、初始化、绘图函数的编写和硬件加速功能的引入等方面内容,可为工程应用中显示控制功能的开发提供参考。
To satisfy the requirement of functional complexity and reduction of developing periods in the field of highly integrated embedded system, this paper presents a method and some kernel points of the graphic drivers development based on WindML, a multimedia developing library in the embedded operating system VxWorks, by taking an example of hardware platform constructed by the ARM9 processor EP9315. The presentation contains the description of the installation and initialization, programing of plotting function and importing of the hardware acceleration about the graphic drivers, in order to offer some reference for the application of display and control function development in projects.
