摘要
由于连续媒体流具有突发性的特点,保证连续媒体应用的服务质量(QoS)往往使得资源利用率非常低.为解决此问题,文中针对连续媒体的特性提出了一种新的任务模型——周期推延任务模型、及基于此模型的连续媒体CPU 调度方法。
Due to bursting of continuous media, guaranteeing QoS of multimedia lead very low resource utilization. To resolve this problem, a new task model called period delayed model is proposed, and a CPU scheduling method for continuous media is brough forward based on this model. The method could provide QoS guarantees of different levels and achieve high CPU utilization.
