I2C-compatible I3C master device and I2C-compatible I3C master-slave device communication system and method

Abstract

The invention discloses an I2C-compatible I3C master device and an I3C master-slave device communication system and method. The I3C master device comprises an MCU module and a processing module, wherein the MCU module is connected with the processing module and is used for sending excitation data to the processing module; the excitation data comprises an intelligent mark set by a user; and the processing module is used for receiving the excitation data sent by the MCU module, analyzing content in the intelligent mark, setting the type of a current communication slave device corresponding to the intelligent mark, sending an instruction signal after a corresponding working frequency to the current communication slave device, connected on an I3C bus, in the type corresponding to the intelligent mark, and receiving a feedback signal of the I3C bus. According to the I2C-compatible I3C master device and the I3C master-slave device communication system, the I3C device using the intelligent mark can be compatible with I2C, the expandability is strong, the logic complexity of an I3C interface is effectively reduced, and information communication can be completed via relatively low 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.

[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
