Problems solved by technology

For an asynchronous FIFO queue with a data bit width as small as 1 bit, the overhead generated by this design is within the acceptable range; but for an asynchronous FIFO queue with a larger data bit width, such as 256 bits, the increased buffering of this design The cost of area and so on is huge

Embodiment Construction

[0042] figure 1 A block diagram of a computer data transmission system of the present invention is shown, and the system includes a computer device 1 , a network device 2 and a server 3 .

[0043] Wherein, the computer equipment 1 includes:

[0044] Check matrix generation module 12, for generating low density parity check code check matrix;

[0045] The structured data encoding module 14 is used for the above-mentioned density parity check matrix to encode the structured data, and convert the structured data into structured data with a preset data encoding format;

[0046] The unstructured data processing module 15 obtains the preset attribute information of each file in the unstructured data, and according to the number N of files in the unstructured data, obtains the structured data with the preset data encoding format and the unstructured data. The N files in the structured data correspond to the N fields respectively, and the preset attribute information of each file in...

Abstract

The invention discloses a computer data transmission system. According to the transmission system, the structured data and the unstructured data are integrated in one file to be transmitted so that the structured data and the unstructured data are enabled to be synchronized in transmission, exchange and sharing in the network, and the problem of data asynchronization in separate transmission can be avoided. According to the method, a free factor rf is introduced to act as a degree of freedom for structured data coding so that the problem of high error floor in a second basis matrix generated under an extension factor zf can be reduced and the reliability of data transmission can be enhanced. The network equipment of the transmission system can determine the clock frequency proportional relation of the data receiving module and the data output module in different clock domains, and the data output rate is controlled by using the counter without using asynchronous FIFO logically so that the risk of data overflow caused by the asynchronous FIFO queues can be avoided.

Description

technical field [0001] The invention relates to the technical field of data communication, in particular to a computer data transmission system. Background technique [0002] Data transmission is the communication process in which data is sent from one place to another. A data transmission system usually consists of a transmission channel and data circuit terminating equipment (DCE) at both ends of the channel, and in some cases, multiplexing equipment at both ends of the channel. The transmission channel can be a dedicated communication channel, or it can be provided by a data switching network, a telephone switching network or other types of switching networks. The input and output devices of the data transmission system are terminals or computers, collectively referred to as data terminal equipment (DTE). The data information sent by it is generally a combination of letters, numbers and symbols. In order to transmit these information, each letter, number, and or symbols...
