Abstract

The embodiment of the invention provides a network-on-chip, a data transmission method and a first switching node, belonging to the technical field of NoC. The network-on-chip is a two-dimensional network-on-chip or a multi-dimensional network-on-chip, each dimension of the network-on-chip comprises at least one unbuffered ring network, each unbuffered ring network comprises a plurality of routingnodes, and at least one of the plurality of routing nodes is the switching node; each unbuffered ring network is intersected with at least one unbuffered ring network, the two intersected unbufferedring networks are in different dimensions and perform data exchange through the switching node; each unbuffered ring network is configured with a dedicated slot and a public slot; at the same moment,only one switching node in each unbuffered ring network has right of use of the dedicated slot, moreover, the right of use of the dedicated slot varies orderly among the switching nodes in each unbuffered ring network, and the right of use of the dedicated slot varies after transmission of data in the dedicated slot is completed.

Description

technical field

[0001] The present application relates to the technical field of Network-on-Chip (English: Network-on-Chip, Abbreviation: NoC), in particular to a Network-on-Chip, a data transmission method and a first switching node. Background technique

[0002] NoC is a new on-chip communication architecture designed for a multi-core system on chip (English: System on Chip, referred to as: SoC). According to the dimension of node arrangement in NoC, it can be divided into one-dimensional NoC, two-dimensional NoC, three-dimensional NoC, etc.

[0003] Taking the two-dimensional NoC as an example, the two-dimensional NoC includes two dimensions, which are respectively recorded as horizontal and vertical. Each dimension may be composed of at least one non-buffer ring network, each non-buffer ring network includes a plurality of routing nodes connected in series to form a ring, and each routing node is used to connect with at least one functional module. The horizontal non-b...

Embodiment Construction

[0050] In order to facilitate the description of the embodiment, the NoC will be described firstly below.

[0051] NoC is a new on-chip communication architecture designed for multi-core SoCs. According to the different NoC dimensions, NoC is divided into one-dimensional NoC, two-dimensional NoC and multi-dimensional NoC. Among them, the dimension of NoC refers to the arrangement direction of nodes in each ring network in NoC, such as the arrangement direction of nodes in each ring network in NoC. The NoC is a two-dimensional NoC. The structure of the NoC is illustrated below with a two-dimensional NoC.

[0052] Such as figure 1 As shown, the two-dimensional NoC includes two dimensions, denoted as horizontal and vertical, respectively. Each dimension may include at least one ring network. Each ring network includes a plurality of routing nodes 10 ( figure 1 ), a plurality of routing nodes 10 are connected in series to form a ring, and at least one switching node is includ...
