| 摘 要： | 在RT-Linux的基础上提出一个能统一支持硬实时、软实时和尽力而为应用的调度框架,在该框架之下,硬实时应用的响应时间短且可预测.对软实时应用进行接入控制,从而可以保证软实时应用的QoS.对尽力而为的应用保留CPU资源,从而保证它不会饥饿.

| Abstract: | In this paper, we presented a scheduling framework which can support the hard real- time applications, soft real- time applications and best- effort applications. In the framework, the response time of hard real time applicatons is short and predictable. In order to provide the QoS, we provide the admission control for soft real- time applications. In order to prevent the best effort applications from starvation, we reserved the CPU for it. |
