摘　　要：AUTOSAR多核操作系统遵循汽车嵌入式软件开发的标准,在快速增加的软件负载下需要保证系统的安全性、实时性要求。仅依靠软件开发人员的经验进行配置常会存在操作系统运行时序上的种种问题,因此需要一种对OS进行监控的方法在开发初期阶段及时发现可能存在的时序错误。针对上述难点,文章提出了一种OS时序的监控方法,并搭建了一套以Infineon AURIX TC397芯片和Vector Davinci工具链为软硬件平台的时序监控系,同时监控系统还包含上位机端软件进行监控数据处理并构建可视化窗口实时还原核内任务运行时序。The AUTOSAR multi-core operating system follows the standards of automotive embedded software development,and needs to ensure the security and real-time requirements of the system under the rapidly increasing software load.Only relying on the experience of software developers for configuration may cause various problems in timing of the operating system.In view of the above difficulties,this paper proposes an OS timing monitoring method and builds a timing monitoring system with Infineon AURIX TC397 chip and Vector Davinci tool chain as software and hardware platform.The monitoring system also includes the upper computer software to process the monitoring data and construct a visual window to restore the running time sequence of tasks in the kernel in real time.
