摘　　要：伴随机载计算平台对算力提升的显著需求,综合化模块化航空电子系统(IMA)采用多核处理器和相应的多核分区操作系统成为必然趋势,从而对目前仅适用于单核处理模式的多分区调度算法产生了进一步的能力扩展需求。面向多核处理的多分区调度算法需要在发挥多核处理效能的同时,继续维持机载安全关键系统的实时性和确定性特征。为此,提出一种基于“绑定组”概念的多分区混合调度方法,支持分区与核资源之间的灵活绑定和确定性调度,取得了“发挥多核处理效能”与“满足关键系统实时、确定性需求”之间的平衡。With the significant demand for computing power improvement of airborne computing platform,it has become an inevitable trend for integrated modular avionics system to adopt multi core processor and corresponding multi core partition operating system,which has further capacity expansion requirements for multi partition scheduling algorithm which is only suitable for single core processing mode.The multi core processing oriented multi partition scheduling algorithm needs to give full play to the multi core processing efficiency and continue to maintain the real time and deterministic characteristics of the airborne system.Therefore,this paper proposes a multi partition hybrid scheduling method based on the concept of binding group,which supports flexible binding and deterministic scheduling between partitions and core resources,and achieves a balance between giving full play to multi core processing efficiency and meeting the real time and deterministic requirements of key systems.
