Embodiment Construction

[0037] An embodiment of the present invention provides a method for bus high-speed communication, including:

[0038] Such as figure 1 Shown:

[0039] Step 101, receiving real-time data or management data sent by the data processing unit;

[0040] Step 102, sending the real-time data or management data to different data channels through the switching device;

[0041] or

[0042] Such as figure 2 Shown:

[0043] Step 201, receiving real-time data or management data received from different data channels through the switch device;

[0044] Step 202, sending the real-time data or management data to a data processing unit.

[0045] The bus high-speed communication method provided by the embodiment of the present invention uses different data channels to transmit real-time data and management data respectively, the real-time data channel transmits real-time data, and the management data channel transmits management data; it should be noted that, in addition to real-time data ...

Abstract

The invention provides a bus high-speed communication method and an interface. Real-time data or management data which are sent by a data receiving and processing unit are sent to different data channels through a switch device; or the switch device receives real-time data or management data from different data channels; the real-time data or management data are sent to the data receiving and processing unit. The invention solves the problem in the prior art that data of different types are transmitted through one data channel, therefore, output speed of the serial bus is increased greatly and efficiency of the serial bus is also improved.

Description

technical field [0001] The invention relates to the communication field, in particular to a bus high-speed communication method and interface. Background technique [0002] High-speed serial bus is used for high-speed data transmission between cards (including master card and slave card). The high-speed serial bus usually uses the master-slave mode and the token mode for data scheduling; the data on the high-speed serial bus is usually divided into real-time data and management data, and the real-time data is exchanged between the master card and the slave card through the high-speed serial bus. Real-time data and management data are used by the master card for configuration, diagnosis and management of slave cards. [0003] These two types of data on the high-speed serial bus have great differences. Real-time data has strong real-time characteristics, requiring high transmission rate and timely response. Usually, the master-slave method is used for transmission, that is, t...
