Introduction Audio and video are the main methods for multimedia applications to provide information to users. These audio and video data generally have a high sampling rate, and the compressed raw data has practical value, otherwise, it will not only occupy a large amount of storage space, but also have a low validity rate during playback or network transmission. Therefore,

1 PCM InterfaceFor different digital audio subsystem, there are several interfaces between microprocessor or DSP and audio devices for digital conversion. The simplest audio interface is the PCM (Pulse coded modulation) interface, which consists of a clock pulse (BCLK), a Frame sync signal (FS), and a receive data (DR) and send data (DX).
