An Energy-Aware Voltage-Frequency Island Partition Method for NoC ∗

To deal with the issues of energy consump- tion for Network on chip (NoC), this paper proposes a method for partitioning an NoC architecture into multi- ple voltage-frequency islands to achieve low energy con- sumption. The method considers the number of Voltage- frequency islands (VFIs), delay and reliability as multi- constraints. A mathematical model for Integer linear pro- gram (ILP) algorithm is constructed and LPSolve is used to solve the issues of VFI partition. The validity of the VFI partition method is accurately verified for E3S and MMS. Simulation results show that the proposed method is more reasonable and smaller consumption can be a chieved while multi-constraints are met. This method can get less energy consumption from 33.6 % to 9.1% or 16.7% than those by the other methods.
