Problems solved by technology

[0004] However, the serial port of the main chip is limited. When there are too many serial devices connected, the main chip does not have enough serial ports to connect other more important serial devices, thus reducing the communication efficiency.

Embodiment Construction

[0054] In order to explain the overall concept of the present application more clearly, the following detailed description will be given by way of examples in combination with the accompanying drawings.

[0055] Such as figure 1 As shown, the embodiment of the present application discloses a chip-based communication method.

[0056] Step 101, the expansion chip receives corresponding first data frames from one or more serial devices.

[0057] In the embodiment of the present application, the first data frame includes: serial port data; the serial port data includes but not limited to one or more of request messages, diagrams, numbers and texts sent by the serial port device to the main chip.

[0058] Step 102, the extension chip determines the serial port identifier of the main chip corresponding to the serial port device and the device number of the serial port device.

[0059] In the embodiment of this application, the extension chip can determine the serial port ID of the...

Abstract

The invention discloses a chip-based communication method. The chip-based communication method comprises the steps that an expansion chip receives corresponding first data frames sent by one or more pieces of serial port equipment; wherein the first data frame comprises serial port data; the expansion chip obtains a second data frame according to the first data frame, the serial port identifier ofthe main chip corresponding to the serial port equipment and the equipment number of the serial port equipment; the expansion chip sends the second data frame to a corresponding serial port on the main chip; and the expansion chip stores the serial port identifier of the main chip and the equipment number of the serial port equipment. The communication efficiency can be improved.

Description

technical field [0001] The present application relates to the technical field of data transmission, in particular to a chip-based communication method and device. Background technique [0002] With the development of communication technology, the core board's ability to process data has become the key to improving communication efficiency [0003] The main chip of the core board includes a plurality of serial ports, which are connected to serial devices through pins in the serial ports. [0004] However, the serial port of the main chip is limited. When too many serial devices are connected, the main chip does not have enough serial ports to connect other more important serial devices, thereby reducing the communication efficiency. Contents of the invention [0005] In order to solve the above problems, in the first aspect, the present application proposes a communication method, including: [0006] The expansion chip receives corresponding first data frames from one or ...
