This parameter specifies the width in bytes of the TDATA signal on each of the AXI4-Stream slave interfaces. The AXI4-Stream master interface TDATA width is this value multiplied by the Number of Slave Interfaces parameter. This parameter is an integer and can vary from 0 to (512/Number of Slave Interfaces). Set to 0 to omit the TDATA signal. If the TDATA signal is omitted, then the TKEEP and TSTRB signals are also omitted. The width of the port is multiplied by 8 to get the width in bits.
