Resumen:
Real-time systems (RTS) are those systems in which results should be produced before a certain deadline [1]. Several design-time schedulability methods have been proposed to guarantee that a set of real-time tasks will meet their deadlines during runtime when they are executed by a processor. Most of these methods have a Computational Cost (CC) that turns them unfeasible to be executed at runtime in a real application. A schedulability method with a high CC could take so much processor time that produces missed deadlines on the real-time tasks analyzed. Consequently, a bounded CC is mandatory for a feasible runtime schedulability method. Several schedulability methods have been proposed to be implemented during runtime.
