Hardware virtualization support for shared resources in mixed-criticality multicore systems

Abstract

Electric/Electronic architectures in modern automobiles evolve towards an hierarchical approach where functionalities from several ECUs are consolidated into few domain computers. Performance requirements directly lead to multicore solutions but also to a combination of very different requirements on such ECUs. Using virtualization in addition is one promising way of achieving segregation in time and space of shared resources. Based on examples taken from the automotive domain several concepts for efficient hardware extensions of coprocessors and I/O devices are shown in this contribution. These provide mechanisms to ensure quality of service (QoS) levels in terms of execution time, throughput and latency. The resulting infotainment architecture is a feasibility study and is integrated into a vehicle demonstrator as centralized infotainment platform (VCT).
