摘　　要：由于工业上对嵌入式系统的实时性要求越来越高,针对Linux的实时性不足进行分析,提出基于Xenomai的双内核解决方案。介绍了Xenomai的基本架构和ADEOS的基本原理,并构建了Xenomai/Linux的运行环境。实验结果表明:基于Xenomai的Linux系统实时性得到了显著提高,能够完成工业中的硬实时性任务。As for the higher requirement to real-time embedded systems in industry, the real time deficiency of Linux system was analyzed, the dual-core solution based on Xenomai was presented. Basic architecture of Xenomai and basic principles of ADEOS were introduced, and the Xenomai/linux operating environment was built. Test results show that based on Xenomai, real time of Linux sys- tem is improved greatly, which can be used to accomplish the task of hard real time in industry.
