Favorable adjustment of periods for reduced hyperperiods in real-time systems

The hyperperiod defines the time span after which the temporal behavior of a periodical real-time system repeats. It is the key property which determines the complexity of both analysis and exhaustive simulation of a given system. Unfortunately, the hyperperiod may easily become very large. We introduce an ILP-based approach to modify the periods in a task set according to user constraints to retrieve an optimal solution for a drastically reduced hyperperiod.Deutsche Forschungsgemeinschaf
