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.
