摘　　要：为使各种实时调度算法能够在Linux环境中得到运行和验证,设计一种Linux系统中的公共多核调度平台。该平台由调度模块和跟踪测试模块组成,调度模块实现系统调用、调度处理以及同步功能,跟踪测试模块实现日志和跟踪功能。测试结果表明,该平台可正确显示调度算法的运行结果。According to the problem that lots of research on the real-time schedule model and algorithm for multi-core platform has not been realized in the real-time operating system,this paper provides a new method to build a public platform in Linux which is composed by two parts.One is the scheduling mode which can realize the functions of the system call and the scheduling process and synchronizing,the other is the tracing mode which can realize the log and tracing the tasks.Experimental results show that it is feasible to work accurate.
