Design of Software in Missile-mounted Computer Based on Embedded Real-time Operating System

摘要:

嵌入式实时操作系统的引入改变了传统弹载计算机软件开发模式;通过对我国自主研发的一款嵌入式实时操作系统进行研究,分析当前战术导弹弹载计算机系统的特征,对实时操作系统实施裁减定制,形成了满足弹载软件系统的微内核系统;围绕着基于该内核系统的应用,某型弹载计算机软件的设计从系统需求分析、任务划分、任务实现以及最终系统运行结果四方面综合给出了设计方法,试验证明,使用操作系统的弹载软件功能、性能满足弹载计算机系统指标要求,对提高软件的可重用性、可靠性等方面起到重要的作用。

Abstract:

Adopting real-time operation system in the missile-mounted computer software changes the traditional development modes. On the base of SZOS for missile system, designing a OS micro-kernel adapt to the tractical missle-mounted computer. Subsequently giving the design of software based on the OS from system requirements analyse, task partition, task realization and measurement data of software running results. The system performance of the software based on embedded real-time operating system is well, it has the vital significance in improving the reusability and reliability.
