Problems solved by technology

[0009] Existing technologies, whether using the basic XY routing algorithm or a specific optimized routing algorithm, regard the entire on-chip network as a unified whole. The optimization based on this idea is faced with large-scale asymmetric on-chip Uneven data transmission on the network often fails to improve overall efficiency

Abstract

The invention provides a network-on-chip design method and device based on a hybrid routing algorithm, and the method comprises the steps: dividing nodes into a controller node, a data processing node, a data exchange node and an equipment node according to the functional characteristics of the nodes in a network-on-chip; arranging the nodes from the central position of the network-on-chip to theperiphery layer by layer according to the sequence of the controller node, the data processing node, the data exchange node and the equipment node; and taking the controller node and the data processing node as a group, taking the data exchange node and the equipment node as another group, and adopting self-adaptive routing between each group, and adopting XY routing or YX routing between the groups. Based on data transmission characteristics and arrangement modes of different types of nodes, data transmission between different nodes is realized by using different routing algorithms, and the performance of the network-on-chip and the whole chip is improved.

Description

technical field [0001] The present invention relates to the computer field, and more specifically, relates to an on-chip network design method and device based on a hybrid routing algorithm. Background technique [0002] With the development of chip technology and the continuous increase in the complexity of application scenarios, for complex function chips that need to cope with complex scenarios, the implementation of a single architecture will cause too high complexity and dependence between different functions, thus greatly prolonging the development cycle. , it is difficult to meet the application requirements. This type of chip (such as mobile phone chips, general-purpose processor chips, AI chips, etc.) has begun to widely adopt an architecture that integrates multiple cores with different functions - different core modules focus on implementing and optimizing specific functions, and then use the bus Communication and collaboration to complete complete chip functions...
