摘要
为了彻底分清SCA中两个容易混淆的关键技术,即CORBA和硬件抽象层技术,采用比较研究的方法,将两者从基本定义、体系结构、应用和实现方法等几个方面进行了深入研究,得出了CORBA和硬件抽象层在一定的应用范围内均可被认为是一种中间件技术;CORBA属于SCA软件架构的一部分,而硬件抽象层则归属为SCA的硬件结构部分;硬件抽象层组件是不能被CORBA直接调用的功能组件等结论,两者都具有屏蔽各种平台间的差异和编程语言不同的特点。
In order to distinguish the two key technologies （CORBA and hardware abstraction layer connectivity） in SCA thoroughly, the basic definition, architecture, applications and implementation methods of the two key technologies are studied, conclusions show that CORBA and hardware abstraction layer connectivity can be considered as a middleware technology within a certain range of applications. The CORBA is a part of SCA software architecture, the hardware abstraction layer connectivity is attributed to the hardware structure of SCA. The hardware abstraction layer connectivity is a functional component, which can not be directly invoked by CORBA and so on, the two technologies can shield the differences between various platforms and programming languages.
