摘　　要：为提高多分区操作系统环境下多核处理器的应用带来的操作系统任务调度的确定性,研究了多分环境下多核操作系统结构,从处理器核心和分区的资源分配和分区调度表的时间同步角度出发,采用了静态配置、处理器绑定和时间窗口调度方法,实现了处理器资源的确定性分配,解决了调度表之间的时间同步问题。测试结果表明,方法有效提高了分区环境下多核操作系统任务调度的确定性。To improve the deterministic problem of task scheduling of the application of multi-core processors under the environment of partition operating system,researched the structure of multi-core processor operating system under the environment of multiple partition,from the perspective of the dispatch of processors resource and the time synchronization of time table,by the method of static configuration,bounding of processors and scheduling of time window,implemented the deterministic dispatch of processors resource and solved the time synchronization between time tables. The test results show that these methods effectively improved the deterministic of task scheduling in multi-core processors under the environment of partition operating syatem.
