Communication-aware Scheduling of AUTOSAR Runnables on Multi-core Systems
Publication Type:
Conference/Workshop Paper

International Workshop on Design Space Exploration of Cyber-physical Systems
Abstract
The AUTOSAR consortium has developed as the worldwide
standard for automotive embedded software systems. From a processor
perspective, AUTOSAR has originally been developed for single-core
processor target platforms. Recent trends and developments have raised
the desire and focused on the potential usage of multi-core processors
for running AUTOSAR-based software. However, inherent in the complex
nature of software execution on multi-core processors, there are
challenges in achieving a resource ecient design of embedded software
systems for multi-core processors. In this paper, we investigate the design
space related challenges in achieving such a resource ecient and
predictable mapping of AUTOSAR runnables onto a multi-core processor.
The goal of this paper is to achieve a design solution that minimize
the runnables' communication cost besides meeting all runnables' timing
and precedence constraints. The main challenges in fullling this
goal are the mapping of AUTOSAR runnables onto a set of tasks and
to schedule the generated task set on a multi-core processor such that
timing and precedence constrains are met while the overall communication
cost is minimized. To address the problem two solution frameworks
are suggested, that each of which contains both mapping and scheduling
phases. In addition, the impact of the communication cost on the overall
system utilization is discussed as a design space parameter for trading
off diffrerent design solutions.
