Vx Works中的中断应用设计要点

Main Points on Interrupt Application Design in VxWorks

硬件中断处理是实时系统设计中的关键性问题,设计人员有必要对其作深入研究,以更好地满足开发工作需要。文中以VxWorks操作系统为软件平台,讨论了在实时系统中进行中断应用设计时要注意的一些问题。由于软硬件的相关性,选用广泛应用的X86架构的嵌入式计算机为硬件平台,对PentiumCPU和计算机主板对硬件中断的管理机制也做了详细介绍。所得出的研究结论在具体的开发项目中均得以验证,可供相关技术人员参考。

Hardware interrupt management is a key problem in real time system and it should be deeply researched by developers to satisfy their job.This paper discusses some important points about interrupt application design in VxWorks.Due to connections between hardware and software,adopting an embedded computer of X86 architecture as hardware platform,the management mechanism for Pentium CPU and computer main board to hardware interrupt is also introduced detailedly.Conclusion of this paper is checked in practice and can be referenced by developers in related fields.
