| 摘 要： | "和欣"操作系统是基于CAR构件技术、支持构件化应用的嵌入式操作系统。"和欣"命名服务机制作为CAR构件的运行环境重要组成部分,在"和欣"中有十分重要的地位。命名服务屏蔽资源的位置特征,由此可以实现资源的透明访问、构件的动态升级和更新。文中分析了"和欣"命名服务的原理、特点及实现,并进一步深化了对面向服务的软件体系架构理解,把面向服务的体系架构引入到了嵌入式领域内,可以提高嵌入式领域内软件开发的灵活性和开发效率。

| Abstract: | "Hexin"is an embedded operating system based on CAR component technology and it supports the application based on component.As an important component of run-time environment of CAR component,"Hexin" named-service occupies an important position on the "Hexin" system.The named-service screens the positional characteristic of resource,as a result,can implement the transparent access of resource and dynamic upgrade and update of the component.Discusses the principal,characteristic and implementation of "Hexin" named-service.It deepens the understanding of services-oriented software architecture and brings such a sofeware architecture into the embedded system,which can imporve the agiliy and the efficiency of sofeware development. |
