Abstract

In the aerospace industry, the highest criticality standard is required for the certification of avionics systems. A multi-core processor with reconfiguration capabilities where safety-critical applications are reallocated once they are affected by faults is one efficient way to enforce such criticality constraints. This paper presents a new model of a task reallocation problem for a reconfigurable multi-core architecture, which allows an execution of lower priority applications when the resources for executing the higher application are insufficient. Furthermore, it provides an implementation of an actual cyber-physical system: the control of a propulsive system with three redundant controllers. In addition to the fault injection mechanisms, a fault recovery capability and a fault detection system based on a majority rule voter are included.
