Problems solved by technology

[0003] The current various embedded system development boards are either learning boards based on relatively low-end processor chips, which can only do some simple programming learning, and cannot perform video and audio development. If they are learning boards based on relatively high-end processor chips The interfaces are not rich enough, especially video and audio interfaces are lacking, and users can only learn related software. The development board cannot realize the design and learning of embedded systems specific to video and audio signal processing

[0004] According to relevant search and research, there are relatively few contents related to modern video and audio technology in college courses at present, and the corresponding practical courses are even more scarce. In addition, in the process of research and development of digital video and audio products in technology companies, the reusability of hardware platforms is very high. Low, not conducive to product cost control and rapid product development and listing
