基于SDL语言的VxWorks嵌入式操作系统的具体实现

EXPLORATION IN HOW TO USE SDL TOOLS IN VXWORKS

随着嵌入式系统通信协议的复杂性急剧提高,迫使工程师们去寻找一种效率更高的设计工具来完成工作,而SDL作为一种图形化的设计满足了这种需要,因此RTOS—SDL相结合的思路应运而生。主要说明了把SDL应用在VxW orks中的步骤和具体实现中遇到的问题,以及编程中的一些技巧。而且经试验表明,采用这种方法不但可以完成原先的需求,而且还可以在有限的时间内完成程序的编写,提高工作效率,对于SDL和嵌入式系统的结合具有很好的参考价值。

The rising complexity of communication protocols forces designers to work with efficient high level software design tools to increase the level of abstraction at which they work. And the SDL was followed for this purpose because it could finish the complex work by graphic flow. So a new advanced RTOS-SDL integration method was brought forward. This paper mainly presents how to use SDL tools in VxWorks and resolve some problems which is met in process of programming. At last, by validated, the results of this method are quite promising and the produced system met the initial specifications within the development time limits and it is beneficial to use SDL tools to design program in the other Embedded System.
