I2S (Inter-IC Sound Bus) is one of the general audio buses applied in various industrial or embedded systems. It only processes the audio data, while other signals like various codes and control signals are transmitted individually. This paper presents an approach how to construct an embedded audio system using the I2S bus to connect relevant supporting code chip and decode chip. This system can reduce the consumption of system resources drastically, therefore fluent WAV broadcast can be guaranteed. Moreover, the familiar media files, such as MPEG1, MPEG2, MP3, MPEG4 can be played through addi...
