Abstract
The number of safety-critical applications is increasing in the automotive domain. Accordingly, requirements given by recent safety standards have to be met in these applications. These requirements include a demonstration of sufficient measures for the handling of permanent and transient hardware faults. Moreover, a consideration of software faults is required. In this work, approaches based on dual-core microcontrollers are investigated with respect to their fault handling capabilities. Therefore, function monitoring architectures that are based on a supervision of the implemented function and generic architectures, which monitor the hardware executing the application, are compared. This comparison is then further illustrated by an application example. Summarizing, both approaches come with their specific advantages and disadvantages, which should be considered during the development of the functional safety concept.
