基于VxWorks操作系统的图形和汉字显示应用研究

Display of Graphs and Chinese Characters Based on VxWorks Operation System

VxWorks操作系统是美国Wind River公司推出的一种嵌入式强实时操作系统,广泛应用在通信、国防、航空、航天等实时性要求较高的领域中。VxWorks在这些领域的使用中,图形显示是必不可少的,尤其是在国内,汉字的显示更加重要。文中论述了在VxWorks操作系统中如何实现图形和汉字显示的方法,介绍了在WindML组件支持下图形显示的配置和应用,并以宋体16×16点阵字库为例具体介绍了该汉字显示开发方案的基本原理与方法。

Embedded real-time operation system VxWorks is produced by U.S. Wind River Company. It is widely used in communication, national defence, aviation and spaceflight fields. In these fields, Graphs display is necessary, and Chinese Characters display is especially more important in China. In this paper how to realize Graphs and Chinese Characters display in VxWorks operating system is discussed. We introduce the application and configuration of Graphs display provided by WindML. The basic principle and methods of Chinese Characters display based lattice are introduced as example on character library.
