【摘要】 利用航电设备测试系统(ATS:AvionicsTestingEnvironment)对实时嵌入式软件进行系统测试是国内外公认的、行之有效的方法。论文对ATS的软件进行了面向对象的分析与设计。将ATS软件分为两大构件——实时构件和非实时构件,分别给出了它们的关键类。非实时构件的关键类是配置工具类,实时构件的关键类是模型类、实时变量类和调度器类。实时调度策略为SBRMS(Segment-BasedRMS)。依据论文成果设计和实现的GESTE已成功地对多个软件进行了系统测试,验证了论文研究成果的正确性和有效性。更多还原

【Abstract】 It is an acknowledged and effective method to test real-time embedded software with ATS(Avionics Testing System).The software of ATS is analyzed and designed with object-oriented method,and hence divided into two system-level components which are real-time component and non-real-time component.Configuration Tool Class is the key class for non-real-time component and Model Class,Real-time Variables Class,Scheduler Class for the real-time component.Real-time scheduling policy is SBRMS(Segment-Based RMS).Designed and implemented hereby,GESTE has successfully been used for system-testing of several softwares,through which both the correctness and the effectiveness of the research fruit are validated.更多还原
