A multicast broadcast communication-aware optical network-on-chip architecture and communication method

Abstract

The present invention proposes a multicast broadcast communication-aware optical network architecture on chip and a communication method, which are used to solve the technical problems of high power consumption and poor scalability of the optical network architecture existing in the prior art, and the communication method The existing technical problems of delay and power consumption are large. In the optical network architecture, the processor modules are divided into clusters arranged in arrays. Each cluster contains an array composed of 2×4 processor modules. Each The processor module is coupled and connected to a first active microring resonator through a coupling port, and the clusters arranged in the array are connected through a serpentine optical waveguide structure and expanded in units of clusters. At the same time, the first active microring resonator and The coupling distance distribution between optical waveguides is set by the power split system principle. In the communication method, the global control unit processes the communication request of the processor module, and sends the obtained control information to the multi-wavelength laser source and the first active microring resonator for network communication configuration.

Description

Technical field [0001] The present invention belongs to the field of communication technology, and in particular, the present invention relates to a network architecture and communication method on a multicast broadcast communication perceived, which can be used to calculate multicast broadcast communication between the processor modules in the system chip. Background technique [0002] As the number of processor cores integrated on a single chip have exponentially growth, the high performance communication between the processor core is the key to the performance improvement of the system. On-board network-based network-based networks can effectively improve processor nuclear communication performance, becoming a preferred solution for nuclear computing systems on the film. With the continuous expansion of the on-chip network and the development of high performance computing applications, the current interconnect-based online network faces the bandwidth, delay, and power consumpt...
