Abstract
The Real Time Operating System (RTOS) supports applications that meet deadlines in addition to providing logically correct results. In multiprocessing operating system for the applications need to meeting of time deadlines and functioning in real time constraints. The quality of real-time scheduling algorithm has a direct impact on real-time system's working.The scheduling algorithms mainly studied in this paper are Earliest Deadline First, Rate Monotonic, Deadline Monotonic, Least laxity First, Group Earliest Deadline First for periodic task.We observed that the choice of a scheduling algorithm is important in designing a real-time system.
