Abstract

Embodiments of the present invention provide a MIPI control circuit and system, a circuit control method, and a circuit system control method. Aiming at the problem that existing smart devices have too many data channels with similar functions, which leads to excessive wiring area occupation, a proposal is made. A MIPI control circuit, comprising: a data analysis module and a switching switch control module; the data analysis module is used to convert and analyze the transmission data; the switching switch control module is used to control the switching of the switch to the corresponding on the working module. By setting the data analysis module to convert and analyze various data, and setting the switch control module to realize the switching of multiple working modules, it solves the problem of repeated wiring design and large space occupation caused by too many MIPI interface devices, and realizes The effect of multiple MIPI devices sharing data lanes and routing.

Description

technical field [0001] The present invention relates to the technical field of mobile processor interface, and more specifically, relates to a MIPI control circuit and system, a circuit control method and a circuit system control method. Background technique [0002] At present, the CPU and LCD of the smart phone perform communication data transmission through the MIPI DSI interface protocol; the CPU and the camera perform communication data transmission through the MIPI CSI interface. The physical layer standard of CSI / DSI is D-PHY, which uses differential signals for transmission, and each screen or camera has 1 to 4 pairs of differential data lines for data transmission. Generally, a screen or camera needs 4-5 pairs of data differential signal MIPI to transmit data, and as the number of LCDs and cameras increases, the number of MIPI signal pairs will also increase. In addition, MIPI wiring needs to be protected by key designs such as ground covering, isolation, equal spa...

Problems solved by technology

And the MIPI wiring needs to be protected by key designs such as ground covering, isolation, equal spacing, equal length, and non-overlapping lines, which requires more wiring space and PCB area

[0003] At present, with the development of smart phones, smart phones with multiple display screens and multiple cameras have appeared. If each camera and each screen is designed with a separate data channel for communication with the processor, it will inevitably lead to a larger PCB area occupied by the data channel. At the same time, under normal circumstances, multi-cameras and multi-displays will not work at the same time, so when one camera or display is working, the rest of the display or cameras are not working
