摘　　要：光片上网络具有带宽高、时延低和传输稳定等优点,然而光信号在光片上网络中进行数据传输时存在串扰噪声和插入损耗,影响通信性能和能耗,且在环境温度发生改变时,影响将进一步加大。光片上网络中的IP核映射将直接影响网络的流量分布,从而对网络的插入损耗和串扰噪声造成影响。文中提出的趋边快速映射算法以温度均衡为目标,通过将网络中的流量均匀分散到网络中以均衡网络温度。仿真结果证明:文中提出的映射算法在实现快速映射的同时,还能减少温度对网络传输能耗的影响。Optical network-on-chip has many advantages,such as high bandwidth,low delay and stable transmission.However,crosstalk noise and insertion loss exist in optical signal data transmission in the optical network-on-chip,which affect the communication performance and energy consumption.When the ambient temperature changes,the influence will be further increased.The IP core mapping in optical network-on-chip will directly affect the traffic distribution of the network,thus affecting the insertion loss and crosstalk noise of the network.The edge-bound fast mapping algorithm proposed in this paper took temperature equalization as the optimization objective,network temperature was equalized by evenly distributing network traffic to the network.Simulation results show that the proposed mapping algorithm can not only realize fast mapping,but also reduce the influence of temperature on network transmission energy consumption.
