Xiangting Wang · Computer Engineering and Applications Journal · 2009
Analyzing common characteristics of scheduling algorithms,this paper proposes a dynamic scheduling algorithm VDDSA based on multi-feature parameters.Considering the value and deadline of the task synthetically,the task scheduling model is established.Furthermore the design way of the priority is given.By adjusting the task’s elasticity coefficient and system’s weight factor,the algorithm has some selfadaptive function.The algorithm is implemented and tested in μC/OS-Ⅱ,and the results show that VDDSA performances well in all workload simulations.
