I2S is an industry standard (invented by Philips) 3-wire interface for streaming stereo audio between devices. Typical applications include digital audio transfer between a CPU/DSP and a DAC/ADC. The I2S core allows a Wishbone master to stream stereo audio to and from I2S capable devices.


- Core is complete and released.
