摘要
分析了嵌入式Linux在实时性方面的不足,针对Linux2.6内核的中断运行机制、内核不可抢占性、自旋锁及大内核锁等问题进行研究,提出相应的实时性改进方法。测试表明,改进后的嵌入式Linux实时性效果较好。
This paper describes the Iimination of real-time performance of embedded Linux,and puts forward corresponding improved methods of Linux 2.6 kernel.These methods focus on interrupt running mechanism,kernel preemption, spinlock mechanism and big kernel lock..According to these tests, the real-time performance of improved embedded Linux is effective.
