Energy saving is one of the biggest challenges designers have to face for Multi-Processor System-on-Chip (MP-SoC) integrating several Processing Elements (PE). In this paper the authors present an adaptive technique to locally adjust the frequency of processing elements on MP-SoC. The proposed method, based on game theory, optimizes the system while fulfilling dynamic constraints. A telecom test-case has been used to demonstrate the effectiveness of their technique. For the evaluated scenario, the proposed technique has obtained up to 20% of latency gain and 38% of energy gain.
