Abstract

The invention provides an MIPI (Mobile Industry Processor Interface) data transmission mode conversion method and device and electronic equipment. The method comprises the following steps: acquiring to-be-converted MIPI command data; analyzing the MIPI command data to obtain effective video data; writing the effective video data into the random access memory according to a preset mapping relation between the effective video data and a write address of the random access memory; reading corresponding target video data from the random access memory according to a preset mapping relation between the MIPI video excitation and a read address of the random access memory; and packaging the target video data and the MIPI video excitation to generate corresponding MIPI video data, and sending the MIPI video data to a video display device. And the conversion cost of the MIPI data transmission mode is reduced.

Description

technical field [0001] The present application relates to the technical field of data communication, in particular to a MIPI data transmission mode conversion method, device and electronic equipment. Background technique [0002] The Mobile Industry Processor Interface (MIPI for short) is an open standard developed for mobile application processors initiated by the MIPI Alliance including companies such as ARM, Samsung, and Intel. Among them, MIPI DSI is a video interface. DSI has two modes: VIDEO mode (video mode) and COMMAND mode (command mode). VIDEO mode does not require the display to integrate Frame Buffer, and COMMAND mode requires the display to integrate Frame Buffer. , In terms of power consumption and cost, both modes have their own advantages and disadvantages. [0003] In the prior art, in order to use the display device of the terminal MIPI VIDEO to replace the display device of the MIPI COMMAND, a dedicated bridge chip is usually used to realize the conversio...
