2.9 Audio interface
The MPS2 and MPS2+ FPGA Prototyping Boards provide a stereo line-level input and a stereo line-level
output.
The audio interface consists of an audio controller in the FPGA, a low-power audio codec, and input and
output stereo audio ports. The audio controller configures the codec over an I
2
C bus. The FPGA and
codec send audio data to each other over an I
2
S bus.
The following diagram shows the audio interface.
