Device and method for realizing point-and-screen adjustment of parallel multi-channel mipi module based on fpga

Abstract

The invention relates to the technical field of MIPI liquid crystal modules, in particular to a device and method for realizing point-screen adjustment of parallel multi-channel MIPI modules based on FPGA. The upper layer software interface divides the data into the same data and different data and sends them to the parameter processing module. The parameter processing module stores and processes them respectively and sends them to the multi-channel control module. The multi-channel control module outputs the same data to each mipi point screen adjustment module respectively. At the same time, different data are transmitted to the corresponding mipi point screen adjustment module according to the corresponding channel number. The mipi point screen adjustment module realizes the conversion of the module point screen, RGB image data to mipi format data, and the mipi parameter adjustment of the module. The present invention reduces the amount of data interaction, reduces the number of software and hardware interaction interfaces, increases the transmission rate, reduces FPGA resource usage and power consumption, is conducive to the stability of system timing, facilitates subsequent function integration, and can truly realize multiple mipi modules Parallel point screen adjustment, and multiple mipi modules do not interfere with each other and are independent.

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.
