Study and implementation of real-time scheduling mechanism based on Linux kernel

LIU Sheng-hui,MA Song School of Software,Harbin University of Science and Technology,Harbin 150080,China  
In the real time system,the task scheduling strategy is the important part of the kernel design.How to process the task scheduling and make sure the task can complete is the important domain in the real-time operating system research.According to the shortcoming in view of the RT-LINUX scheduler when the system near the load or the overload which the performance suddenly drops,an adaptive value-based scheduler is proposed to achieve a high system value by the less deadlines miss.It can be evaluated the performance of the proposed scheduler in terms of two performance metrics,namely,"value ratio" and "success ratio" through both simulation and implementation.
