Real time operating system – Free Udemy Courses

This course contains basics fundamental knowledge of real-time operating systems, Real-time operating systems focus on applications that are running and typically give little importance to applications in waiting. That means fewer tasks or applications are managed, so the system can give more exact results on present execution work. A real-time scheduling System is composed of the scheduler, clock, and processing hardware elements. In a real-time system, a process or task has schedulability; tasks are accepted by a real-time system and completed as specified by the task deadline depending on the characteristic of the scheduling algorithm. In this course, learners will study the basic components of real-time operating systems, Need of RTOS. Different features to select the RTOS. Also, this course focuses on different types of real-time task, like a periodic, aperiodic, and sporadic task. This course includes temporal parameter like Execution time, Absolute deadline, and Relative deadline. It is focused on functional and resource parameters of real-time processes, like Permittivity of jobs, Criticality, optional execution, Laxity type, and laxity function, and resource parameter like resource graphs, and preemptive resources. This course consists of different approaches to real-time scheduling like clock driven, weighted round robin, and priority-driven approach. also explained priority-driven scheduling algorithm with the help of examples.Earliest deadline first , Rate monotonic scheduling, Least slack time, Latest release time scheduling algorithms are explained with the help of examples in very well manner.
