Abstract

The invention provides a data transmission method and device. The method comprises the following steps that: through different protocol interfaces, obtaining a data packet to be transmitted, according to the data message type and the data packet address of the data packet to be transmitted, building a hybrid switch data packet according to the message format of a hybrid interaction message, and sending the hybrid switch data packet; and receiving and analyzing the hybrid switch data packet, obtaining the data packet to be transmitted, the data message type of the data packet to be transmitted and a data packet address, and transmitting the data packet to be transmitted. Through the embodiment of the invention, an HSD (Hybrid Switch Device) message is provided, and the hybrid switch of different communication interface protocols can be realized so as to realize a purpose that various interface protocols are borne on the same physical layer interface to lower equipment complexity and cost.

Description

technical field [0001] The invention relates to the field of electronic communication, in particular to a data transmission method and device. Background technique [0002] In electronic equipment, various communication interface protocols are generally used between chips and devices to meet the communication needs between chips or devices. Communication interface protocol messages include UART (Universal Asynchronous Receiver / Transmitter, Universal Asynchronous Receiver Transmitter), IIC (Internet -Integrated Circuit, integrated circuit bus), CPRI (Common Public Radio Interface, general public radio interface) and other point-to-point methods, and SRIO (Serial Rapid I / O, high-speed interconnection technology), GE (Gigabit Ethernet, Gigabit Ethernet), SPI (Serial Peripheral Interface, serial peripheral interface) and other point-to-multipoint methods. [0003] With the wide application of electronic devices, a large number of communication interface protocols adapted to dif...
