Abstract

In this paper we 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 our technique. For the evaluated scenario, the proposed technique has obtained up to 20% of latency gain and 38% of energy gain.
