Abstract

We have developed real-time middleware which is laid on a POSIX 1003.4,.4a compliant operating system. This real-time middleware supports programming of real-time systems based on rate-monotonic analysis (RMA) and an active object model (real-time object model). RMA is a method to guarantee timing constraints in real-time systems, and an active object model provides us with timing encapsulation for programs. Therefore, the middleware enables us to develop predictable and flexible real-time systems. A data acquisition system, which is a part of a monitoring system, is a target of the middleware. We show that the system is proved to be schedulable as predicted.<>

基于速率单调理论的实时中间件
我们开发了基于POSIX 1003.4的实时中间件。4a兼容的操作系统。这种实时中间件支持基于速率单调分析(RMA)和活动对象模型(实时对象模型)的实时系统编程。RMA是一种在实时系统中保证时间约束的方法,活动对象模型为我们提供了程序的时间封装。因此,中间件使我们能够开发可预测和灵活的实时系统。数据采集系统是监控系统的一部分,是中间件的目标。我们证明了系统是可调度的,正如预测的那样。
