摘要:: 使用UML进行基于框架的实时开发是当今软件发展的一个热点。为了使开发的应用软件支持多平台,Rhapsody实时软件框架将嵌入式操作系统的概念抽象出来,采用了基于抽象操作系统的层次结构。而Rhapsody实时框架中所使用的抽象操作系统和适配器是抽象工厂设计模式在操作系统领域内的一次经典的应用。具体地,通过针对具体的嵌入式Vxworks操作系统给出其Rhapsody实时软件框架适配器实现,并结合一个简单的例子来说明,抽象操作系统和适配器给Rhapsody实时软件框架带来了模块化、可移植性、可复用性等多方优点

Abstract:: The framework-based approach to real-time development with UML is one important aspect of computer software progress.In order to make the development of application software platform-independent,the real-time software framework of Rhapsody uses a layered structure based on the abstraction of the operating system and the concept of embedded operating system is abstracted.The concept of the abstraction of the operating system and the adapter is a classic application of the abstract factory design pattern within the field of operating systems.Then give the implementation of the adapter for the concrete embedded OS Vxworks.Finally,the advantages of real-time framework of Rhapsody with the abstraction of the operating system and adapter,such as modular,portability and reusablity,are introduced by a simple example
