Coreworks, S.A. 
Part Number : CWda18
Overview :
The CWda18 IP core is a configurable multi-channel audio interface component designed to input serial (TDM) digital audio streams from various manufacturers. The CWda18 can be configured at runtime to support an arbitrary number of audio channels (up to 128), and number of bits per sample: 8, 12, 16, 20, 24 and 32 bits. The CWda18 also supports the well known stereo formats: Philips I2S, Left-Justified or Right-Justified. The audio samples are retrieved from a receive FIFO where the channels are ordered and interleaved. A runtime configurable input stage de-serializes the serial audio stream and writes samples to the FIFO in the received order.
Features : - Runtime configurable multi-channel audio serial (TDM) input format
- Supports up to 128 audio channels
- Also supports stereo formats like I2S, Left-Justified or Right-Justified
- Runtime configurable sample width: 8, 12, 16, 20, 24, and 32 bits
- Pre-synthesis configurable sample FIFO depth
- Reports number of samples in FIFO
- Runtime configurable FIFO upper limit threshold: a request is activated when this number of samples in the FIFO is exceeded
- Reports FIFO status: empty, full, almost empty and almost full conditions
- Supports up to 32 bits per sample
- Supports all commonly used sample rates including 8, 11.25, 16, 22.5, 32, 44.1, 48, 96, 192 kHz
- Supports slave or master modes of the audio bus
- Choice of backend interface: AMBATM or CW-Link
