摘要
传统实时系统的设计方法已无法满足现代实时系统对集成、局部验证及柔性的设计要求 ,面向对象的方法是解决这个问题的良好手段 ,但其固有的特性很难满足实时系统的可预测性要求 .为此 ,本文介绍了实时对象的基本思想 ,并根据所采纳实时调度策略对现有的实时对象模型进行了分类与比较 ,最后 。
Traditional real time systems design methodologies have difficulty in addressing requirements of modern real time systems, such as integration, local certifiability and flexibility. Object oriented methodology is a better approach to this problem, but its inherent quality can not satisfy the predictability of real time systems. Therefore, this paper introduces the concept of real time objects, and classifies and analyses the existed real time object model according to real time scheduling method. In the last, we point out their scope of application.
