ABSTRACT
The AUTOSAR multicore operating system lacks support for message-based Multi-Processor System-on-a-Chip (MPSoC) architectures, whereby the advantages [1] of this architecture model for temporal predictability, fault isolation, low overhead, energy efficiency and scalability can not be exploited for AUTOSAR-based systems. Additionally, the current AUTOSAR multicore version limits the autonomy of the cores, which are managed by a common Operating System (OS). Dependencies between cores, for example, by the possibility of activating tasks, task chaining or the setting of alarm / events to other cores, can cause error propagation between cores with permanent and transient hardware errors and design errors. These dependencies require the analysis of the temporal behavior of a core under the influences of the other cores on the MPSoC.
