WebWe firstly have a look at the simplest type of scheduler – the clock driven scheduler. After this we deepen our learning with the fixed priority scheduler and the monotonic schedulers. We learn how the priorities are determined using these schedulers and we learn when/when not to use these schedulers. http://et.engr.iupui.edu/~dskim/Classes/ESW5004/RTSys%20Lecture%20Note%20-%20ch03%20Overview%20of%20Real-Time%20Scheduling.pdf

WebClock-driven schedulers are those for which the scheduling points are determined by timer interrupts. Clock- driven schedulers are also called off-line schedulers because these schedulers fix the schedule before the system starts to run. That is, the scheduler pre-determines which task will run when.
