DaVinci is a DSP and arm dual-core architecture of the SOC chip. The interaction between the chip and the outside is managed via arm-side MontaVista Linux and related drivers and applications, and the DSP end only deals with codec-related algorithms. The communication and interaction between DSP and arm is done through the engine (Engine) and the servers (server).1. Codec engine (

Often we are also accustomed to calling encoding (Encode) serialization (serialization), which serializes objects into byte arrays for network transmissions, data persistence, or other purposes.
Conversely, decoding (Decode)/deserialization (deserialization) restores a byte array read from a network, disk, etc. to the original object (usually a copy of the original object) to facilitate subsequent business logic operations.
When making a remote
When debugging audio codec, it is sometimes necessary to read the value of the codec register to confirm that the register was successfully configured.Remember before debugging wm8978, found this codec register can not read, each read the result is 0xFF.Later on Linux debugging wm8978, with Snd_soc_read () and can read the configured value, I feel very surprised.

Common video coding and decoding standards
Many video codecs can be easily implemented on personal computers and consumer electronics, which makes it possible to implement a variety of video codecs at the same time, which avoids the fact that some dominant codec affects the development and promotion of other codecs due to compatibility. Finally, we can say that there is no such codec
