Abstract: In this paper, study of the classic real-time scheduling algorithms is done. Many papers have been published in the field of real-time scheduling. The problem of scheduling is studied from the viewpoint of the characteristics peculiar to the program functions that need guaranteed service. The quality of real-time scheduling algorithm has a direct impact on real-time system's working. After studied popular scheduling algorithms mainly EDF and RM for periodic tasks with hard deadlines tried to describe performance parameters use to compare the performances of the various algorithms. Observation is that the choice of a scheduling algorithm is important in designing a real-time system .Conclusion by discussing the results of the survey and suggests future research directions in the field of RTOS.
