摘要: Windows操作系统不能直接应用于实时领域。为此,从体系结构、基本系统策略、系统可靠性、实时应用程序开发难度和系统性能等方面,分析比较Windows实时扩展的2个典型产品——RTX和INtime。在此基础上,提出一种基于操作系统自适应域环境的Windows实时扩展方法。理论分析结果表明,该方法的灵活性、可靠性和可移植性优于目前常用方法。

Abstract: Aiming at the problem that Windows can not be used in real-time fields directly because of its real-time faults, Windows real-time extension technology is studied. Common methods of Windows real-time extension are analyzed and compared, and the advantages and disadvantages of each method are summarized. Real Time eXpert(RTX) system and INtime, two typical products of Windows real-time extension, are compared from various angles, such as architecture, system basic mechanism, reliability, difficulty of developing real-time applications and system performance. They are bad at flexibility, reliability, and portability. A method of Windows real-time extension based on Adaptive Domain Environment for Operating System(ADEOS) is proposed.

Key words: Windows operating system, real-time extension, Adaptive Domain Environment for Operating System(ADEOS), Real Time eXpert (RTX) system, INtime system
