Abstract

Several studies have been done to investigate efficient mapping of software components onto a distributed embedded real-time system. However, most of these studies do not consider a distributed system where each node can be a multi-core processor. Mapping becomes even more complicated when precedence constraints between software components are taken into account. In this paper, the ongoing work on addressing the challenge of achieving a resource efficient and predictable mapping of software components onto a distributed multi-core system is discussed. Our goal is to minimize inter-components’ communication cost besides meeting timing and precedence constraints between the components. The solution should solve two sub-problems; assign a set of software components onto a task set, and assign the created task set to (the cores of) the processing nodes. In this paper, we discuss some challenges and potential solutions to design a communication-efficient system.
