Session 3.4: Virtualization

Virtualization Impact on the Performance in Embedded Systems Vortragssprache Englisch

The introduction of virtualization techniques like virtual machine monitors or hypervisors is a current trend in embedded systems. These solutions are leveraged to execute heterogeneous workloads on modern processors or system on chips. The consolidated applications can be as diverse as safety critical real-time applications with strict timing requirements or entertainment programs doing audio and video playback with requirements on connectivity. Such different guest applications may require the usage of more than one operating system to meet the requirements imposed on each individual workload. This paper will look at the impact that the aforementioned guest applications and their underlying operating systems have on each other when consolidated on a single processor. It will also discuss the different tradeoffs that have to be considered in order to make sure that the system design is an efficient one. More specifically, the paper will examine the impact on boot time for safety critical real-time applications as well as multimedia applications, the performance of different types of hypervisors, and the tradeoffs and complications of device sharing between the different guests. Further, this paper will also examine the architectural impact of having safety and security requirements on a system running multiple operating systems and will discuss the specific design considerations that must be made in order to fulfil these.
