摘要
基于组件的软件设计 ,通过复用应用系统中健壮的功能模块 ,更快的构建新系统 ,并且开发成本更低。本文对实时系统的组件设计方法进行了研究 ,提出了一种基于端口对象 (PBO)的组件模型。采用该模型的组件设计方法适用于实时操作系统 (RTOS) ,开发通用的组件层。
Component-based software is desirable to get a system working quickly, to keep costs down, and to reuse the most robust software from prior applications. In this paper, we describe and analysis the component-based software development principles and ways. We present one kind of useful model of port-based object PBO. This model of component described in this paper is targeted specifically to embedded real-time control systems to develop a general component layer.
