Digital Stereo Technology

　　This is project documentation. In here is developed a fully digital HIFI stereo set. Audio data is read from a CD utilizing a standard CDROM drive and routed to a custom made class D amplifier. The amplifier is based on Texas Instruments TAS5504 and TAS5142. All routing and configuration are implemented on the terasic DE1 demo board holding a Cyclone II FPGA. All configurations are using the I2C bus, and all audio is routed using the I2S bus.

　　The NIOS II embedded processor is a key part of the system.
