摘要：

Meeting non-functional requirements, like safety according to ISO26262, is gaining rising importance in the automotive industry along with the reuse and migration of existing applications. Embedded virtualization is a promising technology to isolate software and its possible faults. In a virtualized system shared communication devices constitute a bottleneck and require special treatment for safety-related systems. In this paper, we evaluate the emulation of CAN and Ethernet hardware drivers in virtualized automotive software systems of BMW. We show a methodology how to relocate and isolate safety-related drivers within a large scale software integrated virtualized system. For our analysis we use the Infineon AURIX TriCore TC27x controller. To encapsulate our software, we use a research-based hypervisor supported by ETAS Ltd.
