摘　　要：在嵌入式Linux实时系统中,要求内核对不同时间约束的任务采用不同的调度算法。但目前Linux内核采用单一的实时调度模式,不能灵活地执行多种调度算法,也就无法满足实时系统中实时任务的时间约束。引入了一种能够在Linux内核调度中执行多种调度算法的框架,即通用调度框架(GSF),并改进了其中的多算法调用机制,从而更好地在Linux内核中实现GSF。In embedded Linux real-time system, tasks with different time constraints need kernel to adopt different schedule algorithms, but the current Linux kernel, which has only single real-time schedule mode, can not flexibly implement manifold scheduling algorithms, so it can not meet the demand of time constraints of real-time task in real-time system. A general schedule framework is introduced （GSF）, which can implement manifold scheduling algorithms in Linux kernel, and improved the multi-algorithm calling mechanism in the GSF to make the GSF implement better in Linux kernel .
