Many commercial media/audio players use a large external storage device, such as an SD Card or
CF card, to store music or video files. Such players may also include high-quality DAC devices so
that good audio quality can be produced. The DE2-115 board provides the hardware and software
needed for SD Card access and professional audio performance so that it is possible to design
advanced multimedia products using the DE2-115 board.
In this demonstration we show how to implement an SD Card Music Player on the DE2-115 board,
in which the music files are stored in an SD Card and the board can play the music files via its
CD-quality audio DAC circuits. We use the Nios II processor to read the music data stored in the
SD Card and use the Wolfson WM8731 audio CODEC to play the music.
