摘　　要：通过基于立宇泰S3C44B0X开发板的BSP移植调试,阐述了VxWorks的异常中断处理机制,实现了VxWorks基于S3C44B0X处理器的中断处理,并以外部中断EINT4/5/6/7为例分析了中断的响应过程,满足系统实时性的要求。Through transplanting and debugging BSP on the S3C44B0X board of Liyutai Company, this paper explains the abnormal interrupt handling mechanism of VxWorks and has realized the interrupt processing based on S3C44B0X. Moreover, it analyzes the responding process of external interrupt by taking the example of EINT4/5/6/7 and satisfies the requirement of system real time.
