Torus network based dual-access structures and working mode thereof

Abstract

The invention discloses Torus network based dual-access structures and a working mode thereof. The structure is characterized in that any one router node provides two local interfaces, and the two local interfaces are connected to two different resource nodes; any resource node is accessed to two router nodes in the network in a diagonal manner, two paths of data can be sent to a network-on-chip simultaneously through two connected router nodes, and data from two router nodes is received; and when one router node connected with the resource nodes is occupied, the data can enter the resource node through the other router node connected with the resource nodes. Through adoption of the structure, an average distance between nodes can be shortened, network diameter can be reduced, the parallelism of the network-on-chip can be fully used, the parallel communication capacity between resource nodes can be improved, the throughput of the network-on-chip is greatly increased, the resource node data transmission time is reduced, each resource node can perform binocular computing in a stream mode, and the computing efficiency of the resource node can be improved.

Description

Technical field [0001] The invention relates to a dual access structure based on the Torus network and its working mode, belonging to the technical field of on-chip network communication Background technique [0002] Compared with traditional single-core systems, multi-core systems bring greater advantages in terms of computing power and power consumption. However, with the increase in computing power, it also brings throughput, parallelism, and speed challenges to on-chip communications. . In view of the above problems, the network-on-chip technology is proposed as a communication-centric integrated circuit interconnection structure, and it has become the best solution for multi-core system on-chip communication. With the development of on-chip network technology, researchers have proposed a variety of network topologies.

Problems solved by technology

like figure 1 As shown, in a traditional on-chip network, each routing node can only access one computing unit or storage unit. When the computing unit handles binocular computing, it needs to wait for the two channels of data to be prepared before starting computing. Reduces the speed of computing and processing, affecting the operating efficiency of multi-core systems
