摘　　要：深入分析Linux 2.6内核进程调度算法,为更好的满足Linux系统对嵌入式系统实时可靠性的要求,对现有的调度策略进行分析,指出Linux 2.6内核调度算法的不足,提出基于LFS算法的处理器调度算法,提高了Linux系统的实时性及吞吐量。Linux 2.6 kernel process schedule algorithm is analyzed in depth. In order to meet the requirement of real - time and reliable characteristic to the Linux system, the existent schedule is analyzed. The shortage of Linux 2.6 schedule algorithm is pointed out, and a method of scheduling which based on LFS algorithm is bought forward to improve the real time characteristic and throughput of the Linux.
