摘要: 研究了嵌入式软件可靠性测试平台中仿真器分系统的实现问题.首先介绍了软件可靠性仿真测试平台的功能及组成框架,然后以通用性和可扩展性为前提,对实现仿真器分系统的关键技术进行了探讨,着重对任务调度功能的实现进行了深入研究,提出了一种新的图型任务链的调度方法.实验结果表明,仿真器分系统的这些实现方法具有较高的可靠性、易扩展性和实用性.Abstract: The structure and functions of SRTP(Software Reliability Testing Platform) consisting of main control computer and stimulation computer are introduced. On the basis of expansibility and universality,the study is concentrated on scheduling strategy and key implementation technology in simulation computer,such as real-time network communication,hardware driving method in Windows 98.In this paper,the new technique of graph task chain for task scheduling is proposed and how it can be applied to engineering is discussed.The practical results show that the technology is reliable,expansive and applied.
