A fuzzy-logic based voltage-frequency controller for network-on-chip routers

Abstract

Abstract—Low power design can be easily achieved by scaling the voltage and frequency of the target systems. The most concerning issue is how to make the voltage-frequency scaling adaptable to the required performance of the system at run-time. In this paper, we present the design of a voltage-frequency controller for network-on-chip routers based on fuzzy-logic processing. The communication traffic of a network router will be predicted by a fuzzy-logic algorithm. Then the voltage and frequency of the router will be scaled according to the ...
