Reducing the number of preemptions in fixed priority scheduling
Radu Dobrin, Gerhard Fohler · 2004
Fixed priority scheduling (FPS) has been widely studied and used in a number of applications, mostly due to its flexibility, simple run-time mechanism and small overhead. However, preemption related overhead in FPS may cause undesired high processor utilization, high energy consumption, or, in some cases, even infeasibility.
