Abstract
Using multicore processors in safety-critical systems is a challenge as well as an opportunity. The real parallelism, which may affect synchronization and determinism, leads to a safety-challenge, because new possible interferences might arise. Additionally, redundant software execution is possible within multicore systems. In complex multicore architectures one of the most important challenges is to know the system behavior and the recognition of any variations from the normal system behavior has to be guaranteed. For those cases it is necessary to monitor several states of the system, configurations, timing, etc. To monitor such a complex system a lot of information from the inside of the system needs to be evaluated without affecting the rest of the MPSoC.
