Problems solved by technology

[0003] However, for the current various embedded system development boards, the common ones are learning boards based on relatively low-end processor chips, which can only do some simple programming learning, and cannot be used for image / video digital signal processing development. The learning boards with high-end processor chips have insufficient interfaces, especially video and image interfaces, and users can only learn related software. LCD screen, these defects make these development boards unable to realize the design and learning of embedded systems specific to digital image / video signal processing
[0004] According to relevant retrieval research, there are relatively few contents related to modern image / video technology in college courses at present, and corresponding practical courses are even more scarce. The reusability of the product is very low, which is not conducive to product cost control and rapid product development and launch
