Abstract :
The paper deals with the real-time scheduling of aperiodic OS tasks that composed multiprocessor embedded systems which can change their behaviors at run-time for each reconfiguration scenario. A reconfiguration scenario is assumed to be any run-time automatic addition, removal, or also update of OS tasks according to external events or also user requirements. We propose a new approach to check the system´s feasibility of the tasks while minimizing their response times. An agent-based architecture is proposed to provide run-time technical solutions for users in order to reach again the system´s feasibility after any reconfiguration scenario for the whole multiprocessor embedded systems. We discuss the paper´s contribution by analyzing the experimental results that we did on a running example.
