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...

“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...
PURPOSE: To provide a time control system for a high speed real-time OS by shortening simultaneously the processing time required for insertion to a time wait list and for an interval timer interruption and then fixing these processing time.KUROSAWA HISAYOSHI黒沢 寿好...
Since 1980, thousands of companies have deployed QNX® real-time operating systems to ensure the ideal combination of performance, security and reliability in mission-critical systems. At the core of QNX technology is the QNX® Neutrino® Real-Time Operating System (RTOS), a fully featured ...
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 ...
