摘要:

随着Xilinx公司Virtex5系列FPGA内嵌了Powerpc处理器,嵌入式操作系统VxWorks的加入使构建更为复杂的嵌入式平台成为可能。VxWorks提供的中断处理机制延迟小,符合实时性要求。文中分析了基于Powerpc440处理器的中断处理机制,并详细阐述了中断处理的编程过程。

关键词: VxWorks, Powerpc440, 中断处理, 中断服务程序

Abstract:

As the Powerpc processor is embedded in the virtex5 FPGAs by Xilinx Company,the adding of embedded operating system VxWorks makes it possible to create a more complicated embedded platform.The interrupt handling mechanism provided by VxWorks is of high performance in reducing latency,which is accorded with the real time requirement.In this paper,the interrupt handling mechanism based on Powerpc440 processor is analyzed.Then,the process of interrupt handling programming is described in detail.

Key words: VxWorks;Powerpc440;interrupt handling;interrupt service routine
