:Real time control, diversified functions, system integration and miniaturization are an important development direction of video electronics system. Embedded design based on FPGA can manage system resources more reasonably and effectively, and use limited resources to achieve more complex functions. It will become an important design method to promote the development of video electronics technology. Based on the embedded MicroBlaze microprocessor in V FPGA chip, combined with the model application background and Xilinx embedded development platform, an eight channel gray image channel inconsistency correction algorithm is implemented. On board experiments show the feasibility of applying embedded system to video electronic design, and show its advantages in interface control, storage management, process control, floating-point operation, development efficiency and so on, and it can be applied to real-time image processing of satellite remote sensing camera.
