摘要
飞行模拟器等大型实时多媒体系统采用多处理器架构来处理大量的事件和计算。现有的单处理器系统实时调度算法,如速率单调算法(Rate Monotonic, RM)和最早截止时间优先算法(early Deadline First Algorithm, EDF)在多处理器系统上的性能很差。另一方面,大多数多处理器系统的在线调度算法在实时应用中具有较差的可调度性条件。在本文中,我们研究了在SMP机器上设计实时应用的不同方法。
Designing multimedia applications on real-time systems with SMP architecture
Large real-time multimedia systems such as flight simulators have adopted multiprocessor architecture to handle the large amount of events and computations. Existing realtime scheduling algorithms designed for single-processor systems such as Rate Monotonic (RM) and Earliest Deadline First Algorithm (EDF) have very poor performance on multiprocessor systems. On the other hand, most online scheduling algorithms for multiprocessor systems have poor schedulability conditions for real-time applications. In this paper, we study different ways to design real-time applications on SMP machines.
