Abstract

The present invention discloses a link bridge circuit. The link bridge circuit comprises an I3C slave interface module, a data controller, and a traditional main interface module. The I3C slave interface module is used to connect with an I3C host, and the I3C host implements data exchange based on the I3C communication protocol. The data controller is used to respectively connect with the I3C slave interface module and the traditional main interface module, parse the data transmitted from the I3C slave interface module and the traditional main interface module, and exchange the parsed data with the I3C slave interface module and the traditional main interface module. The traditional main interface module is used to connect with a traditional slave device, and perform the traditional communication protocol-based data exchange with the traditional slave device. According to the link bridge circuit disclosed by the present invention, two-way communication between an I3C host using the I3Ccommunication protocol and a traditional slave device using a traditional communication protocol is implemented, and the implementation cost of the traditional slave device is reduced.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a link bridge circuit, an I3C-based communication system and method. Background technique [0002] With the popularity of smart phones and wearable devices, sensors are becoming more and more common in people's daily life, so research on sensor-related technologies has great market value. [0003] In the field of sensor technology, the existing communication protocols include SPI communication protocol, UART communication protocol and I2C communication protocol. The I3C communication protocol is a new communication protocol based on the I2C communication protocol. [0004] Different communication protocols define data in different ways, so sensor devices using different communication protocols cannot communicate with each other, and data cannot be exchanged with each other. Contents of the invention [0005] The embodiment of the present invention provides a link bridge...
