摘　　要：传统的嵌入式软件测试系统,不论是单机结构还是分布式结构,在长时间大规模的嵌入式软件可靠性测试时,都在数据传输方面存在相应问题。本文针对嵌入式软件可靠性测试对数据通信的实时性、延迟确定性要求,结合在国防、通信、航天、工业控制等领域广泛应用的交换式以太网技术,介绍了一种星型拓扑嵌入式软件测试系统原型。The traditiioal testion system for embedded software system, either a single computer structure or distributed structure, has some problems in data communication while it rtests the reliability of an embedded software system for a long period of time and/or a large scale. This paper introduces a new testing prototyupe for embedded software systems with atar topology structure. The prototype is researched based on the properties of real time communication, delay addurance for embedded software sysyem and exchange Ethernet, which is widely adopted in the areas of national defense, communication, aviation.
