| Abstract: | To meet the demand of smooth scheduling in weakly hard real-time system,the authors firstly expounded a constraint specification based on the window of schedule,and then put forward a W-DBP scheduling algorithm based on traditional DBP to achieve smooth scheduling.The W-DBP algorithm could efficiently solve the problems of fair scheduling and transient overloading that existed in traditional DBP.Simulated analysis and results showed that W-DBP algorithm had a better performance in weakly hard real-time syst... |
| Keywords: | weakly hard real-time system window-distance based priority smooth scheduling constraint specification |
