一种嵌入式Linux实时调度机制改进方案
摘要
在分析传统实时调度器不足的基础上
提出了一种新型智能调度器模型
并通过修改RT-Linux的内核函数
包括实时算法的初始化函数和调度函数
实现了多种调度算法的集成
为用户提供统一的使用界面.最后对新的调度机制进行了算法复杂性分析和性能测试
实验表明
新的调度机制能够较好地满足系统实时性要求.
Abstract
The paper analyses the shortage of traditional real-time scheduler
on the basis that a kind of new intelligent scheduler model is proposed
the model integrates many kinds of scheduling algorithm
namely
the RT-Linux kernel functions
including real-time algorithm initialization and scheduling which are amended
and provides the unification interfaces for users.Finally
the paper carries on the complexity analysis and the performance test to the new scheduling mechanism.Experiments shows that the new scheduling ...
