In recent automotive systems, more and more applications are classified as safety related and hence are assigned an automotive safety integrity level (ASIL) according to ISO26262. Especially in the context of advanced driver assistance systems (ADAS) and automated driving, safety, reliability and availability requirements are ever increasing. In upcoming systems, a classical fail-safe design will not be sufficient in order to fulfill these requirements, and hence fail-operational systems will be essential. This holds especially true when it comes to automated driving levels 4 and 5. On the other hand, well-known approaches from the avionics industry are ill-suited for the use in automotive systems due to space, weight and power (SWAP) restrictions. This motivates the research on new, lightweight approaches for embedded fail-operational systems.

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.
