Uma Abordagem para Estimar Tempos de Execu¸c~ao em Sistemas de Tempo Real baseados em Componentes

Ricardo PerroneRaimundo MacedoGeorge LimaVeronica Lima

Many component-based real-time systems have recently been proposed as a solution to modular and easily maintainable distributed realtime systems. This paper proposes a methodology for estimating probability distributions of execution times in the context of such systems, where no access to component internal code is assumed. In order to evaluate the proposed methodology, experiments were conducted with components implemented over CIAO with the goal to estimate a probability distribution. The collected experimental data show that the proposed approach is indeed a good approximation for component execution time probability distribution.
