In this paper we analyze the traditional model of interrupt management and its incapacity to incorporate reliability and temporal predictability demanded on realtime systems. As a result of this analysis, we propose a model that integrates interrupts and tasks handling. We make a schedulability analysis to evaluate and distinguish the circumstances under which this integrated model improves the traditional model. The design of a flexible and portable kernel interrupt subsystem for this integrated model is presented. In addition, we present the rationale for the implementation of our design over conventional PC hardware and the analysis of its overhead. Finally, experimental results are conducted to show the deterministic behavior of our integrated model.
