Problems solved by technology
[0005] However, in the data processing method provided above, due to the long transmission distance between some ports and VP, the data transmission delay of this port is very large, that is, for the same set of data, other ports may have transmitted the set of data After the multiple data after the group of data arrive at the VP, the group of data transmitted by the port with a longer transmission distance arrives at the VP, resulting in a large amount of buffered data that may be stored in the buffer memories corresponding to other ports. In this way, It is necessary to increase the design of the buffer memory corresponding to the other port, that is, to increase the development and design of the storage resources in the VP

Embodiment Construction
[0047] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0048] Figure 1C It is a schematic diagram of an implementation environment shown according to an exemplary embodiment. The implementation environment mainly includes a plurality of ports 110, a data transmission chain 120, a designated processor 130, and a system controller 140. The designated processor 130 may be a processor such as VP, which is not limited in this embodiment of the present invention.
[0049] Wherein, the data transmission chain 120 includes sequentially connected multi-stage data chain bus nodes (Chainbus Node) 120a, and the multi-stage data chain bus nodes 120a are connected to the plurality of ports 110 in a one-to-one correspondence. The data link bus node with the shortest transmission distance between the mu...

The invention discloses a data processing method and device and belongs to the technical field of communication. The method comprises the steps of receiving a global pulse signal which is sent by a system controller and is used for indicating time to transmit data of multiple ports, and a first indication signal which is at least used for indicating a port to which the currently transmitted data belongs; and when a rising edge of the global pulse signal is detected, transmitting the data of the multiple ports to appointed processors based on the first indication signal and multiple preset delay threshold values in one-to-one correspondence with the multiple ports, thereby enabling the appointed processors to carry out precoding based on the received data. For the same group of data transmitted at the multiple ports, in the process of transmitting the data of the various ports in the group of data to the appointed processors, the data of the various ports is controlled to be transmitted to the appointed processors in an alignment mode, in this way, memories do not need to be increased in the appointed processors, and the development of storage resources in the appointed processors is reduced.
Description
technical field [0001] The present invention relates to the field of communication technology, in particular to a data processing method and device. Background technique [0002] With the rapid development of communication technology, high-band data transmission services are widely used. In the high frequency band data transmission system, usually use multi-port data transmission, please refer to Figure 1A ,Should Figure 1A It exemplarily shows a schematic framework diagram of data transmission through 8 ports, where different ports correspond to different transmission lines. However, when the distance between different transmission lines is relatively close, crosstalk is likely to occur, which will affect the performance of the system. [0003] At present, in order to solve the crosstalk problem, before multi-port data transmission, the data transmission system precodes all the data to be transmitted, and increases the reverse crosstalk factor, that is, in the data trans...
