Description

Technical Field

[0001] The present invention belongs to the technical field of chip development, and in particular relates to a connection diagram establishment method and a data transmission mechanism. Background Art

[0002] Data transmission is a key element throughout the function and implementation of the chip. It not only affects whether the chip can successfully achieve the intended function, but also directly determines the chip's performance indicators, energy consumption levels, reliability, and ability to adapt to different application scenarios.

[0003] At present, the commonly used technical method for data transmission between chip nodes is to add a random and globally unique ID to the data of each sending node in the chip as the identity of the data. Under this scheme, the sending node and the receiving node must first perform a handshake to pre-store matching information before data transmission before data transmission can be performed. This not only requires more hardware storage resources, which not only makes the handshake before data transmission greatly affect the efficiency of data transmission, but also because of the multiple pre-stored matching information, a large amount of hardware storage resources are occupied. Summary of the invention

[0004] In order to solve at least one of the problems mentioned in the above background technology, the present invention proposes a connection graph establishment method and a data transmission mechanism.

[0005] A connection graph establishment method and data transmission mechanism, the process is as follows:

[0006] Step S1, in a system on chip, marking all closed connection graphs;

[0007] Specifically, in a system on chip, if the sending node and the receiving node are closed connected, the connection relationship between the sending node and the receiving node is marked as a closed connection graph; the closed connection connection includes: one-to-one connection between the sending node and the receiving node, one-to-many connection between the sending node and the receiving node, many-to-many connection between the sending node and the receiving node, and many-to-one connection between the sending node and the receiving node;

[0008] Step S2, in the compilation phase, generating a configuration list for all sending nodes and receiving nodes in the closed connection graph;

[0009] The configuration list contains the configuration information of each sending node and receiving node. Specifically, the configuration information includes: the receiving address of the data, the sending type of the data and the length of the data.

[0010] Step S3, marking the data in the same closed connection graph;

[0011] Specifically, for the connection relationship that conforms to the closed connection graph, according to the position of the data in the transmission, the data located at the front end of the transmission is defined as upstream data, and the data located at the back end of the transmission is defined as downstream data, and the upstream data and downstream data are marked with the same ID as the prefix;

[0012] The ID is globally unique in the closed connection graph. The present invention proposes to distinguish the position of each piece of data in the upstream and downstream by adding a prefix to the upstream and downstream data.

[0013] On this basis, the present invention proposes to use a configuration list and a prefix ID to establish a connection between the sending node and the receiving node, without the need to cache the matching information between nodes online, nor the need for an additional connection to transmit the matching information. The method and mechanism proposed by the present invention not only save hardware resources, but also simplify the connection steps when matching upstream and downstream nodes, and improve the efficiency of data transmission between chip nodes.

[0014] Step S4, the marked data is transmitted in the closed connection graph according to the information in the configuration list;

[0015] First, the sending node reads the prefix ID of the data and reads the receiving address of the data in the configuration list according to the prefix ID;

[0016] Then, the prefix ID of the data and the receiving address of the data are spliced, and the spliced data is sent;

[0017] Next, the receiving node receives the data sent by the sending node, parses the prefix ID of the data from the received data, and looks up the receiving address of the prefix ID locally;

[0018] Finally, the receiving node reads the configuration information of the prefix ID in the configuration list according to the parsed prefix ID, and writes the data according to the receiving address of the prefix ID.

[0019] In the actual implementation process, the sending node and the receiving node are decoupled from each other. There is no need to wait for the sending and receiving of data to be completed, and other data can be sent and received.

[0020] The present invention proposes that, compared with the existing technology, it has the following beneficial effects:

[0021] The present invention proposes to use a configuration list and a prefix ID to establish a connection between the sending node and the receiving node, without the need to cache the matching information between nodes online, and without the need for an additional connection to transmit the matching information. The method and mechanism proposed by the present invention not only save hardware resources, but also simplify the connection steps when matching upstream and downstream nodes, and improve the efficiency of data transmission between chip nodes. Description of the Drawings

[0022] Figure 1 is the process schematic diagram of the present invention;

[0023] Figure 2 is the structural schematic diagram of the closed connection graph in the embodiment of the present invention. Detailed implementation manners

[0024] In order to make the objectives and features of the present invention more obvious and understandable, the following describes the technical solution in detail through embodiments and with reference to the accompanying drawings.

[0025] As Figure 1 shown, a method for establishing a connection graph and a data transmission mechanism are implemented as follows:

[0026] Step S1, in a system on a chip, mark all closed connection graphs.

[0027] Specifically, in a system on a chip, if the connection between the sending node and the receiving node is a closed connection, the connection relationship between the sending node and the receiving node is marked as a closed connection graph.

[0028] As Figure 2 shown, the closed connections include: one-to-one connection between the sending node and the receiving node, one-to-many connection between the sending node and the receiving node, many-to-many connection between the sending node and the receiving node, and many-to-one connection between the sending node and the receiving node.

[0029] Step S2, in the compilation stage, generate a configuration list for all the sending nodes and receiving nodes in the closed connection graph.

[0030] The configuration list contains the configuration information of each sending node and receiving node. Specifically, the configuration information includes: the receiving address of the data, the sending type of the data, and the length of the data.

[0031] Step S3, mark the data located in the same closed connection graph.

[0032] Specifically, for the connection relationship that conforms to the closed connection graph, according to the position of the data in the transmission, the data located at the front end of the transmission is defined as upstream data, and the data located at the back end of the transmission is defined as downstream data, and the upstream data and downstream data are marked with the same ID as the prefix.

[0033] Step S4, the marked data is transmitted within the closed connection graph according to the information in the configuration list.

[0034] First, the sending node reads the prefix ID of the data and reads the receiving address of the data in the configuration list according to the prefix ID.

[0035] Then, splice the prefix ID of the data and the receiving address of the data, and send the spliced data.

[0036] Next, the receiving node receives the data sent by the sending node, parses the prefix ID of the data from the received data, and looks up the receiving address of this prefix ID locally.

[0037] Finally, the receiving node reads the configuration information of the prefix ID in the configuration list according to the parsed prefix ID, and writes the data according to the receiving address of this prefix ID.

[0038] In the actual implementation process, the sending node and the receiving node are decoupled from each other. Without waiting for the completion of data sending and receiving, other data can be sent and received.

[0039] So far, according to the method disclosed in the present invention, the working process of the present invention has been implemented once.
