| 摘 要： | 把运用于商务应用和桌面系统的中间件和构件化开发思想应用于分布式实时嵌入式(DistributedReal-timeandEmbedded,DRE)软件领域是当前的一个热门研究话题。CORBA构件模型(CORBAComponentModel,CCM)解决了跨平台语言无关的构件化开发问题,然而在提供QoS保证上CCM存在设计缺陷。论文首先分析了CCM的总体构架,接着提出了一种支持DRE软件开发的新的构件模型Z-CCM,这种构件模型从构件的实现框架、装配过程和运行时环境三方面对CCM进行了优化,以改进CCM在提供QoS保证上的缺陷,从而可以提高DRE软件的开发效率,文章最后介绍了Z-CCM的应用背景。

| Abstract: | Applying thinking of middleware and component base d development used in business and desktop system into DRE software is currently a popular topic.CORBA Component Model(CCM)solves issues for component based deve-lopment in multi-platform and language independence while there is limitation for QoS assurance provision.First this paper illuminates overview of CCM.Then a new component model named Z-CCM is raised which optimizes provision of QoS assurance in CCM from component implementation framework,packaging and deployment ,runtime environment ,thereby development productivity for DRE software will be increased.Application of Z-CCM is introduced at the end of paper. |
