Investigation on AUTOSAR-Compliant Solutions for Many-Core Architectures

Abstract

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.

Modelling multi-criticality vehicular software systems: evolution of an industrial component model

“…real-time operating system, along with modelling languages able to capture all the characteristics of vehicular applications. In this respect, we extended RubusMM (the Rubus metamodel formalising its component model) according to the virtualisation design option, as described in [61], which enables the reuse of the certified Rubus Kernel. The Rubus Kernel is certified according to the ISO 26262 standard ASIL D while Rubus ICE (i.e.…”

Redundant dataflow applications on clustered manycore architectures

“…First support for multicore processors was added in version 4.0 of AUTOSAR. However, the AUTOSAR multicore extensions were only designed for a simple hardware model in which cores access the main memory and other peripherals over a shared bus [4]. To meet the requirements of future automotive applications, there is great interest in extending the existing multicore capabilities and adding support for additional hardware architectures like clustered manycores [4,12,22].…”
