Abstract
This research paper deals with reconfigurable real-time systems to be adapted to their environment under userrequirements. A reconfiguration scenario is a run-time software operation that allows the addition, removaland update of real-time OS tasks which can share resources and should meet corresponding deadlines. Wepropose a new Reconfigurable Priority Ceiling Protocol (denoted by RPCP) that avoids deadlocks after anyreconfiguration scenario and changes the priorities of tasks in order to reduce their response and blockingtimes, and to meet their deadlines. This protocol requires the use of two virtual processors in order to guaranteethe non-interruption of execution during the reconfiguration step. We develop a tool that encodes this protocolwhich is applied to a case study.
