Abstract
The real time scheduling algorithm plays an important role in the real time systems.The test for scheduling algorithm is a very important step.The static priority scheduling algorithm and the dynamic priority scheduling algorithm are two kinds of scheduling algorithms on real time systems.Analyses the condition and the problem for EDF scheduling algorithms.Present a method for testing scheduling algorithm based on the response time of tasks in the worst condition for simple model and complex model.Determine the basis to realize this real-time scheduling algorithm for the practical application.
