答:实时系统(Real Time System)是指产生系统输出的时间对系统至关重要的系统。从输入到输出的滞后时间必须足够小到一个可以接受的时限内。 RTOS与通用计算机OS的区别: A. 实时性。响应速度快,只有几微秒;执行时间确定、可预测; B. KB,节省内存空间,降低成本; C. 应用程序开发较难; D. 需要专用开发工具:仿真...
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...
简介:【4月更文挑战第8天】软件体系结构 - 实时操作系统(Real-Time Operating System, RTOS) 实时操作系统(Real-Time Operating System, RTOS)是一种专门设计用来满足实时应用需求的操作系统。这类系统的主要特征在于其对时间敏感任务的高度响应能力和确定性,确保在规定的时间限制内准确无误地完成关键操作。以下是关...

“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...
Back-fore Ground System Work Flow 2. RTOS 系统 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。
real-time system designers must program their applications carefully with priorities in mind. In a typical real-time application, a designer will place time-critical code (e.g. event response or control code) in one section with a very high priority. Other less-important code such as logging ...
