Problems solved by technology

The parallel transmission method refers to the simultaneous transmission of data bits (bits), which is characterized by fast transmission speed, but when the transmission distance is long and the number of bits is large, the communication line is complicated and the cost is increased.
The serial transmission method refers to the sequential transmission of data bit by bit. Its characteristic is that the communication line is simple. Only a pair of transmission lines can realize two-way communication, which greatly reduces the cost. It is especially suitable for long-distance communication, but the transmission speed is relatively slow.

Embodiment Construction

[0015] The basic idea of ​​the present invention is to combine the parallel and serial transmission modes in the baseband transmission to realize another transmission mode. In terms of hardware architecture, the present invention adds one or more data transmission lines on the basis of serial lines, and remains unchanged for other lines (that is, on the basis of the previous transmission pins being unchanged, add one or more Transmission data pins, and increase the control format that can control the transmission of multiple data lines), use the same hardware performance with the original data lines or on the basis of the original, different transmission methods can be realized for different data transmission lines, this It is necessary for the controller and the device to have functions and hardware implementations of multiple transmission methods.

[0016] A data transmission device according to an embodiment of the present invention such as figure 1 As shown, it includes a...

Abstract

The invention discloses a data transmission method and a data transmission device for providing a serial and parallel combination transmission mode between a transmitting end and a receiving end. A plurality of control lines and a plurality of data lines are connected between the transmitting end and the receiving end, and the data lines can be increased based on a primary serial structure. The method comprises the following steps: packing data to be transmitted into a plurality of data packets according to the data lines and the data transmission mode at the transmitting end and distributing the data packets onto the plurality of data lines respectively; transmitting the plurality of data packets through the plurality of data lines respectively, wherein the data lines transmit the data packets in a serial mode; and receiving a plurality of data blocks at the receiving end respectively and recovering the data blocks into original data.

Description

technical field [0001] The present invention relates to data transmission, in particular to a data transmission method and device. Background technique [0002] Currently, in baseband transmission, there are two transmission modes, serial and parallel. Parallel transmission refers to the simultaneous transmission of data bits (bits), which is characterized by fast transmission speed, but when the transmission distance is long and the number of bits is large, the communication line is complicated and the cost increases. The serial transmission method refers to the sequential transmission of data bit by bit. Its characteristic is that the communication line is simple. Only a pair of transmission lines can realize two-way communication, which greatly reduces the cost. It is especially suitable for long-distance communication, but the transmission speed is relatively slow. Contents of the invention [0003] For this reason, the present invention provides a data transmission m...
