Synthesizing Energy-Optimal Controllers for Multiprocessor Dataflow Applications with Uppaal Stratego

Streaming applications for mobile platforms impose high demands on a system’s throughput and energy consumption. Dynamic system-level techniques have been introduced, to reduce power consumption at the expense of performance. We consider DPM (Dynamic Power Management) and DVFS (Dynamic Voltage and Frequency Scaling). The complex programming task now includes mapping and scheduling every task onto a heterogeneous multi-processor hardware platform. Moreover, DPM and DVFS parameters must be controlled, to meet all throughput constraints while minimizing the energy consumption.
