On-Chip Optical Router for Hybrid Switching

Abstract

The invention discloses an on-chip optical router for hybrid switching, which mainly solves the problems of high communication delay, low network transmission efficiency and low resource utilization rate facing a single exchange mechanism in the existing on-chip optical router. The router comprises an OCS (Optical Circuit Switching) part and an OPS (Optical Packet Switching) part, wherein each part is composed of an electric field module and an optical field module, the OCS electric field module establishes an optical link for the OCS optical field module according to electric link establishing information before transmitting messages, and the OPS electric field module provides control information for the OPS optical field module in a transmitting and switching process of optical packets. The OCS part is used for transmitting the messages for using an OCS switching mechanism, and the OPS part is used for transmitting the messages for using an OPS switching mechanism. The on-chip optical router respectively optimizes performances of different types of messages, has the advantages of less communication delay, high network transmission efficiency and high resource utilization rate, and is suitable for interconnections and communications in an on-chip optical network.

Description

technical field [0001] The invention belongs to the field of communication technology, and further relates to an on-chip optical router for hybrid switching in the field of Optical Network-on-Chip (Optical Network-on-Chip) communication technology, which can be used for communication between processor cores of the Optical Network-on-Chip. Background technique [0002] The rapid development of semiconductor technology and integrated circuit technology promotes the continuous increase of the scale of System on Chip (SoC), and makes it develop towards the direction of multi-core and heterogeneous. However, the traditional SoC is designed based on the bus, and there are bottlenecks in bandwidth, synchronization, reusability, scalability, etc. The specific performance is as follows: (1) The communication bandwidth is limited. The bus can be shared by multiple users, but its serial access mechanism determines the communication method. A bus cannot support more than one pair of use...
