Embodiment Construction

[0014] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0015] The present invention is based on the I2C bus interface protocol. Simple supplements are made on this basis to realize a new multi-data line interface compatible with the two-line I2C interface. One clock line and multiple data lines are adopted, and one of the data lines is completely in line with I2C bus interface protocol, slave address, read and write control flags, start and stop flags are only transmitted on this data line, and the rest of the data lines are only used for data transmission, data response, and the data line strobe signal and strobe response Signal, the data line can tra...

Abstract

The invention discloses an inter-integrated circuit (I2C) bus control system. The system comprises a bus host device and a bus slave device, wherein the bus host device is communicated with the bus slave device through an I2C bus; the I2C bus comprises a path of clock wire and multiple paths of parallel data wires; and the multiple paths of parallel data wires are used for transmitting data between the bus host device and the bus slave device in parallel. After the method is adopted, the system is compatible with I2C protocols, and under the same frequency, the processing capacity of the system can be increased exponentially.

Description

technical field [0001] The invention relates to an I2C bus control system and method. Background technique [0002] In modern electronic equipment, chips using I2C interface are very common. I2C has the advantages of simple interface and flexible configuration. As the performance of electronic equipment is getting higher and higher, the processing capability of the chip needs to be continuously improved, and the original bus speed cannot meet the requirements, and the transmission rate of the bus is required to continue to increase, but the I2C transmission mechanism limits the bus rate to not be too high. Aiming at this problem, we propose an implementation method of the I2C bus system with multiple data buses, so that the processing capability can be doubled at the same frequency. Contents of the invention [0003] The purpose of the present invention is to provide a method for realizing a multi-data line I2C bus control system. [0004] The present invention is realiz...
