摘要
多任务处理是北斗导航接收机设计的关键环节,本文采用μC/OS-Ⅱ实时操作系统,完成了在北斗导航接收机中的多任务处理及任务间的通信,解决了实时性、稳定性的问题。研究并设计了接收机的系统结构、系统的多任务的划分以及采用消息队列进行任务之间的通信。试验表明μC/OS-Ⅱ完全能够满足系统的要求。
Multitask processing is a crucial aspect in the design of Beidou navigation receiver. This paper interprets the means of embedded real-time operating system μC/OS-Ⅱ ,completes multitask processing and communicating between tasks, resolves the problem of real-time performance and stability. Study,multitask compartmentalizing and communicating between tasks using message queue. The experimental results shows μC/OS-Ⅱ can meet the need of system.
