An i3c master device compatible with i2c, i3c master-slave device communication system and method

Abstract

The invention discloses an I2C-compatible I3C master device, an I3C master-slave device communication system and a method. The I3C master device includes an MCU module and a processing module; the MCU module is connected to the processing module for sending incentive data to the processing module; the processing module, It is used to receive the incentive data sent by the MCU module. The incentive data includes the smart tag set by the user; parse the content in the smart tag, and set the type of the current communication slave device corresponding to the smart tag; the type corresponding to the smart tag connected to the I3C bus The current communication slave device sends the command signal corresponding to the working frequency; and receives the feedback signal of the I3C bus. The I2C-compatible I3C master device provided by the present invention and the I3C master-slave device communication system can use smart tags. The I3C device is compatible with I2C. The invention has strong scalability and effectively reduces the logic complexity of the I3C interface, enabling it to complete information communication with lower power consumption.

Description

technical field [0001] The invention belongs to the field of integrated circuit IP core design, and in particular relates to an I2C-compatible I3C master device, an I3C master-slave device communication system and a method. Background technique [0002] The full name of IP core is intellectual property core (Intellectual Property Core), which refers to a chip design module provided by a certain party. Designers can use IP cores as the basis for ASIC or FPGA (English full name: Field Programmable Gate Array, Chinese full name: Field Programmable Logic Gate Array) logic design to shorten the design cycle and improve design quality and efficiency.

[0003] MIPI (English full name: Mobile Industry Processor Interface, Chinese full name: Mobile Industry Processor Port) Alliance has proposed a new standard specification for I3C. A simple, two-way two-wire synchronous serial bus) feature of the new interface standard, when compatible with I2C, using the pure traditional I2C mode to be compatible with the I2C bus will cause any feature advantages of I3C to be unable to be utilized, and will cause I3C Interface logic complexity and power consumption increase
