针对高性能低功耗的片上网络设计问题，提出一种多重约束下的电压频率岛划分方法．该方法以优化片上网络系统总能耗为目标，综合考虑电压频率岛个数、传输延时及网络中各PE节点的可靠性等多重约束条件，构建了适用于ILP的数学模型以解决片上网络的电压频率岛划分问题．使用LPSolve求解器对所建模型求解，并从E3 S测试基准中选用多组测试用例和一个多媒体系统实例，验证了该方法的有效性．实验结果表明，该电压频率岛划分方法可在满足多重约束条件的同时，更加合理地划分片上网络的电压频率岛，有效地降低网络能耗．相比于随机划分方法和其他经典的划分方法，该方法可降低能耗9．1％～33．6％和16．7％．

To design the network-on-chip (NoC)with high performance and low power,a voltage-frequency islands (VFI)partition method with multi-constraints is proposed.Aiming at optimizing the energy consumption of NoC,the proposed method considers the number of voltage-frequency islands,delay and reliability as constraints.A mathematical model for the ILP (integer linear pro-gramming)algorithm is constructed and LPSolve is used to solve the problem of VFI partition.The validity of the VFI partition method is verified by several test cases chosen from the benchmark E3 S and MMS (multimedia systems).The experimental results show that the proposed VFI partition method is more reasonable and achieves lower power while all the constraints are met.This method can get less power consumption from 9.1%to 33.6%and 16.7%than those by random method and other classic methods.
