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...
“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...

In the day to day life, we come across many such gadgets and appliances which work on RTOS. For example, our alarm clocks, washing machines, microwave ovens, etc.Types of Real Time Operating SystemsThere are two types of Real-Time Operating System: 1) Hard Real-Time OS and 2) Soft ...
RTOSes are designed to handle multiple processes at one time, ensuring that these processes respond to events within a predictable time limit. Processing in an RTOS occurs within defined time constraints. The priority of tasks is monitored and the system can change task priority. Systems that are...
A real-time operating system includes multiple components: The scheduler: This is the main RTOS element that determines the order of execution of tasks or threads usually based on a priority scheme, and either in a run to completion or round robin fashion. Some RTOS may try to load balance ...
"A real-time system is one in which the correctness of the computations not only depends upon the logical correctness of the computation but also upon the time at which the result is produced. If the timing constraints of the system are not met, system failure is said to have occurred."...
It is very important to improve the design of the real-time operating system (RTOS) especially if we want to use it in some special devices. Numerous researches have accepted conventional RTOS as being the customary approach for designing devices used by children. This is because these are able...
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.
The answer depends on the system you are building. If that system is a car driving along a freeway at 70mph, an unmanned aerial vehicle, or an industrial robot on a production line, then the system must be guaranteed to respond to a particular condition in a very short space of time....
