Multi-cast broadcast communication perception optical on-chip network architecture and communication method

Abstract

The invention proposes a multi-cast broadcast communication perception optical on-chip network architecture and a communication method, and is used for solving technical problems in the prior art thatan optical on-chip network architecture is higher in power consumption and is poorer in extendibility and the technical problems that a communication method is bigger in time delay and power consumption. In the optical on-chip network architecture, a processor module is divided into clusters which are arranged in an array, and each cluster comprises an array which is formed by 2*4 processor modules. Each processor module is coupled to one first active micro-ring resonator through a coupling port. The clusters in the array are connected through a snake-shaped optical waveguide structure, and are in unit extension. Meanwhile, the coupling distance distribution between the first active micro-ring resonator and the optical waveguide is set by a power separation system. In the communication method, a global control unit performs the processing of the communication request of the processor modules, and transmits the obtained control information to a multi-wavelength laser light source to perform the network communication configuration with the first active micro-ring resonator.
