Abstract :
Recent automotive systems exhibit an increased susceptibility against transient hardware faults. As a consequence, dependability measures are mandatory to provide appropriate fault detection or masking properties fulfilling the required safety standards. On the other and, production costs are still a crucial factor in this domain, which leads to hardware consolidation and therefore mixed-criticality systems. An existing dependability approach, supporting such systems, combines triple modular redundancy with encoded operations, but still leaves the operating system as single point of failure. We intend to close this gap by extending the encoded operations throughout the kernel execution, and additionally integrate the analyzed system behavior into the code.
