2. Earliest deadline first scheduling - Wikipedia

   en.wikipedia.org/wiki/Earliest_deadline_first...

   Earliest deadline first (EDF) or least time to go is a dynamic priority scheduling algorithm used in real-time operating systems to place processes in a priority queue. Whenever a scheduling event occurs (task finishes, new task released, etc.) the queue will be searched for the process closest to its deadline.

3. Least slack time scheduling - Wikipedia

   en.wikipedia.org/wiki/Least_slack_time_scheduling

   Least slack time (LST) scheduling is an algorithm for dynamic priority scheduling. It assigns priorities to processes based on their slack time. Slack time is the amount of time left after a job if the job was started now. This algorithm is also known as least laxity first.

4. Fixed-priority pre-emptive scheduling - Wikipedia

   en.wikipedia.org/wiki/Fixed-priority_pre-emptive...

   Fixed-priority preemptive scheduling is a scheduling system commonly used in real-time systems.With fixed priority preemptive scheduling, the scheduler ensures that at any given time, the processor executes the highest priority task of all those tasks that are currently ready to execute.

5. Deadline-monotonic scheduling - Wikipedia

   en.wikipedia.org/wiki/Deadline-monotonic_scheduling

   Deadline-monotonic priority assignment is a priority assignment policy used with fixed-priority pre-emptive scheduling. With deadline-monotonic priority assignment, tasks are assigned priorities according to their deadlines. The task with the shortest deadline is assigned the highest priority. [1]

6. Earliest eligible virtual deadline first scheduling - Wikipedia

   en.wikipedia.org/wiki/Earliest_eligible_virtual...

   It uses notions of virtual time, eligible time, virtual requests and virtual deadlines for determining scheduling priority. [1] It has the property that when a job keeps requesting service, the amount of service obtained is always within the maximum quantum size of what it is entitled.

   Some commonly used RTOS scheduling algorithms are: [5] Cooperative scheduling; Preemptive scheduling. Rate-monotonic scheduling; Round-robin scheduling; Fixed-priority pre-emptive scheduling, an implementation of preemptive time slicing; Fixed-Priority Scheduling with Deferred Preemption; Fixed-Priority Non-preemptive Scheduling
