摘　　要：设计并实现一种应用于μC/OS-Ⅱ系统的中断底半部机制。该机制与内核本身提供的信号量、消息邮箱等机制位于同层,同时支持有优先级的中断底半部静态触发和无优先级的动态注册。在大型海洋资料浮标项目中的应用结果表明,该机制可有效提高系统的响应速度和稳定性。For μC/OS-Ⅱ doesn＇t support bottom half interrupt,this paper presents an implementation scheme of bottom half mechanism for μC/OS-Ⅱ.According to the priorities of interrupts,it can be triggered statically by some special interrupts with priorities,and it also supports dynamic registration for interrupts without priorities.This mechanism improves the system performance.This mechanism has already been achieved,and used in ocean data buoy system successfully.Result shows that it can improve the system response speed and stability.
