| 摘要: |
| 多媒体应用的出现对操作系统调度模型提出了新的要求, 许多多媒体系统中既有硬、软实时应用程序, 又有传统的分时应用程序, 希望在同一操作系统框架内得到支持。本文提出了支持上述功能的CPU调度模型, 并设计了两种算法来实现该模型: 基于QoS的CPU带宽划分算法和双优先级调度算法。 |

| Abstract: |
| The advent of multimedia application calls for new scheduling paradigms in operating system. The new paradigm should be able to handle the combination of hard real-time、soft real-time and conventional application present in many multimedia systems. This paper proposes a CPU scheduling model supporting the functions described above. The paper proposes two algorithms to implement this model: QoS-based CPU bandwidth partitioning algorithm and two-level priority algorithm. |
