Fail-operational in safety-related automotive multi-core systems

Abstract

Dynamically expendable real-time systems are an essential improvement over current future automotive E/E architectures. New functions and applications like automated driving or the subsequent activation of features require a different approach. This also applies to existing architectures which lack enhanced safety concepts beyond common fail-safe systems. Especially, electronic components without mechanical fallback require a fail-operational implementation to guarantee a correct safety-behavior. Although common hardware architectures already provide a couple of safety features, hardware-supported features to realize such systems are under research. In our work-in-progress paper we provide an overview on existing approaches and present future concepts for the implementation of fail-operational systems on a multi-core processor.
