An Efficient Scheduling of AUTOSAR Runnables to Minimize Communication Cost in Multi-core Systems
Publication Type:
Conference/Workshop Paper
Venue:
The Seventh International Symposium on Telecommunications
Abstract
The AUTOSAR consortium has developed as the
worldwide standard for automotive embedded software systems.
From a processor perspective, AUTOSAR was originally
developed for single-core processor platforms. Recent trends
have raised the desire for using multi-core processors to run
AUTOSAR software. However, there are several challenges in
reaching a highly efficient and predictable design of AUTOSARbased
embedded software on multi-core processors. In this paper
a solution framework comprising both the mapping of runnables
onto a set of tasks and the scheduling of the generated task
set on a multi-core processor is suggested. The goal of the
work presented in this paper is to minimize the overall interrunnable
communication cost besides meeting all corresponding
timing and precedence constraints. The proposed solution framework
is evaluated and compared with an exhaustive method to
demonstrate the convergence to an optimal solution. Since the
exhaustive method is not applicable for large size instances of the
problem, the proposed framework is also compared with a wellknown
meta-heuristic algorithm to substantiate the capability of
the frameworks to scale up. The experimental results clearly
demonstrate high efficiency of the solution in terms of both
communication cost and average processor utilization.
