和欣嵌入式系统命名服务机制研究

Study of Named-Service Mechanism on Embedded OS of Hexin

"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。

＂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 prlncipal,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.
