Problems solved by technology

In order to improve production and testing efficiency, it is necessary to perform parallel point-screen adjustment on multiple mipi modules. Usually, only time-sharing adjustment can be realized by software, and real-time parallel adjustment cannot be achieved. Therefore, it is necessary to use fpga to realize parallel adjustment function. If Implemented by instantiation (hardware description terminology, that is, copying intact) multiple channels, each channel contains mipi adjustment function, which is a parallel processing method
Since several channels need to be instantiated, the data interaction of several channels needs to be transmitted, and each channel contains control signals, image data, etc., and the amount of data is doubled, which will lead to a large amount of data interaction between software and hardware, and a long time for data interaction. Not conducive to system stability
At the same time, instantiating multiple channels also doubles the FPGA resource consumption, and the remaining resources are limited, which is not conducive to the increase of new FPGA functions.

Abstract

The invention relates to the technical field of MIPI liquid crystal display modules, and in particular relates to a device and method for realizing parallel multi-channel MIPI (Mobile Industry Processor Interface) module screen touch adjustment based on a FPGA (Field Programmable Gate Array). An upper software interface sends data including same data and different data to a parameter processing module; the parameter processing module respectively stores and processes the data and sends the data to a multi-channel control module; the multi-channel control module respectively outputs the same data to each MIPI screen touch adjustment module, and simultaneously transmits the different data to the corresponding MIPI screen touch adjustment module according to a corresponding channel number; and the MIPI screen touch adjustment module realizes module screen touch, conversion from RGB (Red Green Blue) image data to data in the MIPI format and MIPI parameter adjustment of the module. According to the invention, the data interaction amount can be reduced; the number of software and hardware interactive interfaces can be reduced; the transmission rate is increased; the FPGA resource utilization rate and the power consumption thereof are reduced; the time sequence stability of the system is facilitated; subsequent function integration is convenient; parallel screen touch adjustment of a plurality of MIPI modules can be really realized; and furthermore, the plurality of MIPI modules are not interfered with each other and independent respectively.
