存在另外一种调度算法:动态调度算法,即任务的优先级不是固定的。文章中的deadline-driven scheduling algorithm是一种动态调度算法,该调度算法的思想:任务的优先级根据其截止时间调整,截止期越近的任务优先级越高,即EDF调度算法。 针对文章中提出的任务集,EDF调度算法可以让所有的任务都被调度,而RM调度算法没法保证。...

刘教授是计算机实时系统领域的开山祖师,他在1973年发表的论文Scheduling Algorithms for Multiprogramming in a Hard-Real-Time Environment可以称得上开天辟地,他在这篇论文中提出了著名的Liu&Layland上限,这一理论也成为了计算机实时系统设计的基本准则。许多实时系统中的问题都来源于此,例如多核处理器出现之后,实时系统从...
This book is a basic treatise on real-time computing, with particular emphasis on predictable scheduling algorithms. The main objectives of the book are to introduce the basic concepts of real-time computing, illustrate the most sig nificant results in the field, and provide the basic ...
