SCA中间件技术浅析

Analysis on Middleware Technology in SCA

针对软件通信体系结构规范(SCA),研究了SCA中间件技术。以SCA软件体系结构为基础,描述了公共对象请求代理(C0RBA)中间件技术在SCA中的作用和优势,探讨了SCA体系中中间件对硬件平台模块化的技术支持,分析了为确保SCA架构下软硬件独立性对硬件组件进行抽象所采用的硬件抽象层(队L)和实时C0RBA技术方法,并阐述了两种技术方法各自的优缺点。

Aiming at software communication architecture specification, this paper researches on middleware technology in SCA. Based on SCA software communication architecture, the paper describes the role and advantages of CORBA middleware technology in SCA, discusses the technology support of the middleware for hardware platform modularization in SCA, analyzes the hardware abstraction layer （HAL） and real-time CORBA methods to abstract hardware components for ensuring the independency of software and hardware in SCA architecture, and presents the advantages and disadvantages of this two methods.
