【摘要】 在现代嵌入式操作系统中,中断处理技术是一项重要的技术.通过中断技术,使得处理器能够和外设并行地工作,提高了CPU的执行效率.首先结合了软件和硬件两个方面分析arm-μ clinux的中断处理技术,然后基于SEP3203微处理器介绍了中断向量表的软件实现,最后通过网络设备中断例程的注册阐述了如何实现用户中断例程的安装.更多还原

【Abstract】 Interruption technique is very important in an embedded system.With this technique,processor and periphery equipments can work together and CPU can work more efficiency.It analyzes the interrupt-technique within the arm-μClinux system from hardware to software,and then,introduces the interrupt vector table based on the SEP3203 processor particularly.The initialization of the interrupt vector and the net device’s ISR register are discussed.更多还原
