IP Description: 

"CWda16 IP core is a configurable stereo audio interface component designed to input a serial digital audio stream. The CWda16 supports the well known I2S interface format originally developed by Philips and also the Left-Justified or Right-Justified serial audio formats. The CWda16 can be configured at runtime to support two (16, 20, 24 or 32 bit) audio channels read from two different addresses in an interleaved manner, or two 16-bit audio channels read in parallel from the same register.
