虚拟机(VM)被部署在嵌入式系统上,以在同一物理平台上集成具有不同运行时要求的多个应用程序。在自动驾驶汽车等场景中,这些虚拟化平台必须处理不同的应用需求-从严格的时间可预测性到高性能-同时满足不同的约束,如能源效率,热边界和系统寿命。为了解决这些挑战,我们提出了CHIPS-AHOy,一个可预测的整体网络物理学Hypervisor,它将虚拟机隔离机制与新的资源分配方法集成在一个整体的决策适应循环中,以实现运行时的可预测性,同时管理能源,热量和磨损的限制。我们提出了几个现实的MPSoC平台上的实验结果表明,芯片AHOy实现可预测的操作,同时节约能源,管理温度和延长系统寿命的能力。
Virtual machines (VMs) are being deployed on embedded systems to integrate multiple applications with different run-time requirements on the same physical platform. In scenarios such as autonomous vehicles, these virtualized platforms must handle varying application requirements - from strict temporal predictability to high performance - while simultaneously satisfying disparate constraints such as energy efficiency, thermal bounds, and system lifetime. To address these challenges we presentCHIPS-AHOy,a prediCtableHolIstic cyber-PhySicAlHypervisOr that integrates VM isolation mechanisms with novel resource allocation approaches within a holistic observe-decide-adapt loop to achieve run-time predictability and simultaneously manage energy, thermal and wearout constraints. We present experimental results on several realistic MPSoC platforms that demonstrate the ability of CHIPS-AHOy to achieve predictable operation while conserving energy, managing temperature and extending system lifetime.
