Method and node for determining transmission path of information

Abstract

The invention provides a method and node for determining a transmission path of information. The method comprises the following steps: determining the type of the current node according to a position relation of the current node and a fault ring; determining the next hop node for transmitting the information according to the type; and transmitting the information to the next hop node. Therefore, an optimized fault-tolerant transmission path can be determined in the communication process, thereby saving the link resource and guaranteeing the real-time validity of the communication.

Description

technical field [0001] The embodiments of the present invention relate to the communication field, and more specifically, to a method and a node for determining a transmission path of information. Background technique [0002] A network-on-chip ("NoC" for short) has become a development trend of many-core systems. The grid mesh structure and the planar silicon chip geometry can be well matched, and provide better scalability and higher bandwidth than the one-dimensional bus or single ring structure. At present, NoC systems generally adopt 2D-mesh structures, such as Teraflop80 core and Tilera64 core. [0003] When the number of nodes increases, some nodes may be necrotic during chip production, and some nodes will become hot spots in actual use, and their lifespan will be shorter than other nodes. Currently, the concept of partition or region for nodes on the NoC is proposed, that is, a part of the nodes are formed into a small area system to complete a certain task indepe...

Problems solved by technology

When the nodes determine the transmission path of information through this method during the communication process, it will cause waste of link resources and reduce the real-time effectiveness of communication.
