WebNov 8, 2016 · Figure 1. Both possible outcomes for static-priority scheduling with two tasks (T1=50, C1=25, T2=100, C2=40) Setting priorities. The rate monotonic algorithm (RMA) is a procedure for assigning fixed priorities to tasks to maximize their "schedulability." A task set is considered schedulable if all tasks meet all deadlines all the time. WebIn rate-monotonic scheduling algorithm a static priority policy with preemption is used. Whenever a high priority process arrives it will preempt a lower priority process. Every process gets the priority according to its period. Lower the period higher is the priority. Also, the processing time remains the same in each period.

WebJan 16, 2024 · Least Slack Time (LST) is a dynamic priority-driven scheduling algorithm used in real-time systems. In LST, all the tasks in the system are assigned some priority according to their slack time. The task which has the least slack time has the highest priority and vice versa. Priorities to the tasks are assigned dynamically. t : Real time when ...
