I2S

Transmitter: is a wrapper that instantiates a controller and an i2s transmitter. It is expected to
have an N-bit left and N-bit right channel defined by g_chan_width as well as a sample input defined by g_samp_width. The module also contains a g_addr_width generic that allows the user to set the FIFO address width which translates into the depth of the FIFO. A g_master generic allows the controller to generate the ws_master signal or to act as a slave and receive the ws_slave signal.

Receiver: is a wrapper that instantiates a controller and an i2s receiver. It is expected to have an N-bit left and N-bit right channel defined by g_chan_width as well as a sample input defined by g_samp_width. The module also contains a g_addr_width generic that allows the user to set the FIFO address width and a g_master generic that allows the controller to generate a ws signal or to act as a slave and receive a ws signal.

Transmitter w/ AXIS: is a wrapper that has all of the functionality of the Transmitter but with AXIS inputs. It has 2 additional generics, g_packet_size that allows the user to set the number of data samples per AXIS packet and g_header_size that sets the number of headers per AXIS packet from 0 to 3. These headers will be removed from the AXIS packet and not transmitted over the I2S bus.

Receiver w/ AXIS: is a wrapper that has all of the functionality of the Receiver but with AXIS outputs. It has 2 additional generics, g_packet_size that allows the user to set the number of data samples per AXIS packet and g_header_size that will be used for the receiver to output optional headers on the AXIS output. The header data will be coming from the module inputs header_1, header_2, and header_3 as needed.

Transceiver: a combination of the Transmitter and Receiver.
