| 摘 要： | 当前星载嵌入式实时操作系统将各个功能模块都集成在内核之中,这导致内核庞大,增加了内核出现bug的风险,从而使整个操作系统的可靠性降低.设计并实现了一个基于微内核的星载嵌入式实时操作系统,通过将功能模块以任务方式运行在用户态,任务间通过消息传递机制通讯,以减少内核代码量.最后测试表明设计达到故障隔离的效果.

| Abstract: | All functional modules of Satellite Real Time Operating System are integrated into the kernel at present,leading to the enormous kernel and augmenting the bugs in the kernel,and the reliability of the whole operating system is decreased.A Microkernel-Based Satellite Real Time Operating System is designed and implemented in this paper,All functional modules run as tasks in user-level,all tasks are communicated by the Message Passing Mechanism to decrease the size of the kernel.Higher reliability is gained wi... |
