Summary:Many real-time embedded systems execute multi-mode applications, i.e. applications that can change their functionality over time. With the advent of multi-core embedded architectures, the system design process requires appropriate support for accommodating multi-mode applications on multiple cores which share common resources. Various mode change and resource arbitration protocols, and corresponding timing analysis solutions were proposed for either multi-mode or multi-core real-time applications. However, no attention was given to multi-mode applications that share resources when executing on multi-core systems. In this paper, we address this subject in the context of automotive multi-core processors using AUTOSAR. We present an approach for safely handling shared resources across mode changes and provide a corresponding timing analysis method.
