摘　　要：快速准确是S3C44BOX向量中断的特点,但在有关文献中对此的介绍不利于初学者的学习和使用。详细分析了以ARM7为内核的S3C44BOX向量中断的实现,移植嵌入式操作系统μC/OS-Ⅱ,进行液晶显示任务的创建和调度,实现电力监控器大尺寸彩色液晶显示。实际运行表明,工作稳定可靠,人机交互友好。Nicety and speed is the feature of S3C44BOX＇s vector interruption,but the introduction about it in relevant papers is not suitable for the new learners to grasp the technique. First, the paper narrates in detail the realized procession of the S3 C44BOX＇s vector interruption. Then, port the embedded operation system μC/OS - Ⅱ in S3C44BOX and use it to create and distribute displaying task. Thus man - machine interface of power monitor is realized. Practically running shows that man - machine interface is friendly and steady.

关 键 词：嵌入式系统 向量中断 任务创建 任务调度
