A Fault-Tolerant Real-Time Scheduling Algorithm in Software Fault-Tolerant Module
2007
In software fault-tolerant module, the key issue that affects the performance of fault-tolerant scheduling algorithm is how to predict precisely whether a primary is executable. In order to improve the prediction precision, a new algorithm named DPA, Deep-Prediction based Algorithm, is put forward. DPA uses prediction-table to predict whether a primary can be completed before it is scheduled. Simulation results show that DPA provides more execution time for primaries and wastes less processor time than the well-known similar algorithms.
