摘　　要：针对L inux系统在实时应用中的技术障碍,首先分析嵌入式内核实时性不足的主要原因。然后分析和研究了多任务,双内核和任务分割三种改善嵌入式实时性能的不同方法,并对它们各自的优缺点进行比较。研究表明,嵌入式实时内核性能有很大的改进空间。Aiming at technology obstacle which Linux system is applied in real - time, the paper first analyzes the primary reason which the embedded kernel real -time is deficient. Then analyze and research three different methods which improve the embedded real- time performance, including multi - duties, double kernel and duty division. And the strongpoint and shortcoming of them are compared. Research indicates that embedded real - time performance has great improvement room.
