近年来，在开发用于硬实时系统的分析技术方面有相当多的活动。不可避免地，这些技术使简化的假设，以减少要解决的问题的复杂性。不幸的是，这导致了理论和工程实践之间的差距。本文提出了新的分析，使成本的调度程序（时钟开销，队列操作和释放延迟）被纳入标准方程计算最坏情况下的响应时间。除了预测现实系统的真实行为外，该分析还允许确定时钟中断率等自由参数。>
There has been considerable activity in recent years in developing analytical techniques for hard real-time systems. Inevitably these techniques make simplifying assumptions so as to reduce the complexity of the problem to be solved. Unfortunately this leads to a gap between theory and engineering practice. The paper presents new analysis that enables the costs of the scheduler (clock overheads, queue manipulations and release delays) to be factored into the standard equations for calculating worst-case response times. As well as predicting the true behavior of realistic systems, the analysis also allows free parameters, such as clock interrupt rate, to be determined. >
