“…Bradatsch [33] compared two different implementation strategies for OS service calls, message and lock based, in a shared memory multicore implementation of AUTOSAR. Evaluation on a 2 and 4 cores processor showed clear advantages of the lock-based approach.…”

As of today, AUTOSAR is the de facto standard in the automotive industry, providing a common software architecture and development process for automotive applications. While this standard is originally written for singlecore operated Elec-tronic Control Units (ECU), new guidelines and recommendations have been added recently to provide support for multicore archi-tectures. This update came as a response to the steady increase of the number and complexity of the software functions embedded in modern vehicles, which call for the computing power of multicore execution environments. In this paper, we enumerate and analyze the design options and the challenges of porting AUTOSAR-based automotive applications onto multicore platforms. In particular, we investigate those options when considering the emerging many-core architectures that provide a more scalable environment than the traditional multicore systems. Such platforms are suitable to enable massive parallel execution, and their design is more suitable for partitioning and isolating the software components.
