| Abstract: | Based on the analysis of the limitation of embedded Linux in real time application, the paper proposesd some improvement methods of real time Linux with the double kernel method, fine - grain timer mechanism, non - interruptive kernal and real time scheduling policy. After improvement, the new kernel was more efficient and real time performance was enhanced. |

| Keywords: | embedded system real time real time scheduling policy |
