In this paper we analyze the traditional model of interrupt management and its inability to incorporate the reliability and temporal predictability demanded by real-time systems. As a result of this analysis, we propose a model that integrates interrupts and tasks handling. We introduce a novel implementation of this model that uses an adaptation of the optimistic interrupt protection technique [12] for achieving predictability and low overhead. The detailed design of a flexible and portable kernel interrupt subsystem for this integrated optimistic model is presented. We make a schedulability analysis to evaluate the optimistic integrated model and perform experiments to verify its deterministic behavior and its overhead
