Multicores, being the latest state-of-the-art technology, gain more and more importance in automotive and aerospace systems. This technology will not only be used in infotainment and non-safety-critical applications but will also be introduced in upcoming safety-critical systems. At the moment, various commercial off-the-shelf processors are available that are, however, not built for such applications. In order to ensure correct system behavior, online monitoring can be used for processors targeting infotainment or general purpose applications. The cores and other bus masters within the MPSoC compete for the exclusive use of shared resources like a memory controller. It is of high importance to provide guarantees of usage in such cases, e.g. in terms of access time and rates.
