Application circuit diagram of I3510 codec

Hi3510 comes with Linux operating system (also supports open operating systems such as Vxworks, WinCE) and ARM processor, so that the chip can realize many rich application function development in addition to the encoding and decoding functions. As shown in Figure 2, as long as a common AD is added, the digitization, compression, storage and transmission functions of the composite video signal can be realized. The Hi3510 development kit provides an upper-level API interface, which can be called to realize all chip functions and develop its own personalized functions. Figure 3 shows the application design of the chip encoding scheme.

The decoder application is the same as the encoder in terms of architectural design (convenient schemes can be kept consistent, and a set of hardware can be used to meet different requirements, and only software upgrades are required). The decoder only needs to be equipped with a DA chip (if it is an LCD digital screen, the chip can be saved) to realize the function of decoding the data code stream, and realize the menu operation of user human-computer interaction through GUI or OSD, and realize the application of products with similar functions such as PMP. Figure 4 shows the application design of the chip decoding scheme.
