VxWorks下基于ML507嵌入式系统的中断处理

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Powerpe440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。%As the Powerpc processor is embedded in the virtex5 FPGAs by Xilinx Company, the adding of em- bedded 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 re- al 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.
