摘　　要：随着多核处理器在嵌入式领域广泛使用,在提升装备处理性能的同时也带来了一系列不确定性问题。为了提高多核实时操作系统中任务调度的确定性,本文针对确定性调度的影响因素,结合当前分区调度和多核调度的优点设计出一种确定性多核任务调度的理论方法,主要包括资源的静态配置、空间分区在多核上的部署分配、时间分区的设计和时间同步,并将在锐华高安全操作系统实现中加以实践应用。As multi-core processors are widely used in the embedded field,while improving equipment processing performance,it also brings a series of uncertainties.In order to improve the certainty of task scheduling in multi-core real-time operating systems,for deterministic scheduling Influencing factors,combined with the advantages of current partition scheduling and multi-core scheduling,designed a deterministic theoretical method of multi-core task scheduling,which mainly includes static allocation of resources,deployment and allocation of space partitions on multi-core,time partition design and time synchronization.And it will be applied in the implementation of Ruihua high security operating system.
