The invention provides a three-dimensional optical network-on-chip based on a ring control optical network and a communication method thereof for solving the technical problems of singleness of a wavelength using method and the like in the prior art. The three-dimensional optical network-on-chip comprises an electric layer, an optical transmission network layer and an optical control network layer, wherein the electric layer comprises N clusters, the optical transmission network layer comprises N transmitting / receiving units connected by a ring transmission optical waveguide, the optical control network layer comprises N control units connected with a ring notice optical waveguide and a ring arbitration optical waveguide respectively, the three layers form a stacked structure, and the three-dimensional optical network-on-chip is formed by connecting TSV (Through Silicon Vias) with a TSV pad; the three-dimensional optical network-on-chip dynamically adjusts the quantity of wavelengths used when data packets are transmitted according to the length of the data packets and the magnitude of a network load, and arbitrates wavelength resources used when data packets are transmitted in a manner of absorbing or releasing optical pulse signals, thereby realizing intra-cluster communication, inter-cluster communication and multicast / broadcast communication between IP cores.

Description

technical field [0001] The invention belongs to the technical field of communication, and relates to an optical on-chip network system and a communication method, in particular to a three-dimensional optical on-chip network based on a ring control optical network and a communication method thereof, which can be used for on-chip multi-core communication. Background technique [0002] Limited by physical limits, it is no longer feasible to improve the performance of single-core processors simply by reducing transistor size and increasing frequency. Adopting multi-core architecture design is an inevitable trend in the future development of System-on-Chip (SoC). The focus has shifted from multi-core system design to many-core or even thousand-core system design. With the increasing number of IP (Intellectual Property) cores integrated in SoCs, inter-core communication issues become the key to multi-core system design. Network-on-Chip (NoC) with good communication performance, g...
