RTOS全称为:Real Time OS,就是实时操作系统,强调的是:实时性。 实时操作系统又分为硬实时和软实时。 硬实时要求在规定的时间内必须完成操作 ,硬实时系统不允许超时。 在软实时里面处理过程超时的后果就没有那么严格。 在实时操作系统中,我们可以把要实现的功能划分为多个任务,每个任务负责实现其中的一部分,每个任务...
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...

Real-time Ubuntu is now generally available Welcome to this three-part mini-series on real-time Linux. In Part I, we set the stage for the remainder of the series by defining a real-time system, and went through common misconceptions. We also covered the broad market applications of a...
List of open source real-time operating systems. Dive deep into features, comparisons, and use-cases to choose the perfect real-time operating system for your project. Stay updated with the latest in the RTOS world.
“Soft” Real-Time OSs In general, an operating system (OS) is responsible for managing the hardware resources of a computer and hosting applications that run on the computer. An RTOS performs these tasks, but is also specially designed to run applications with very precise timing and a high...
Our architecture enabled us to safety-certify QNX® OS for Safety, so you can focus on what you build—not the OS you built it on. Real-Time Availability System resources are available when needed and tasks complete when they are supposed to. ...
