Perspective view of virtualization technologies for avionics system

摘要: 将虚拟化技术应用于航空电子系统的设计,利用虚拟机系统来实现硬件资源的共享管理和软件子系统的划分,并符合ARINC 653规范的要求——模块化、可靠性、隔离性与开放性.构建由硬件平台、虚拟机监视器(VMM,Virtual Machine Monitor)和分区操作系统、航电应用软件所组成的3层软件架构,可以满足综合模块化航电系统(IMA,Integrated Modular Avionics)的功能要求与接口要求.其中,为实现符合ARINC 653要求的VMM,传统分区操作系统需要进行多项关键性调整,包括处理器特权级和特权指令、中断、内存地址空间分配、设备驱动等方面,从而可以构造基于VMM的综合化航空电子系统.

Abstract: Virtualization technology was used to achieve the designing of avionics system. Virtual machine system was used to implement a sharing management of hardware resources and to make a partitioned schema for software sub-systems subject to the requirements of ARINC 653, which required that the avionics system should be featured with modularity, reliability, isolation and openness. A triple-layer architecture, composed with hardware, virtual machine monitor(VMM)/partitioning OS, avionics application, was implemented to meet the functional and interfacing requirements of integrated modular avionics(IMA), which was a highly integrated and modularized avionics system. In order to achieve these features, VMM should be modified to resolve some problems so as to be compatible with ARINC 653 and traditional partitioned operating system should also be modified with several critical components or mechanisms, such as processor privilege level and privileged instruction, interrupt trap, memory management, device drivers and so on. With these improvements, a VMM-based IMA system could be constructed.-
