Table: AXI4-Stream Data Interface Signal Descriptions describes the AXI4-Stream signal names and descriptions.

IMPORTANT: In Table: AXI4-Stream Data Interface Signal Descriptions , TotalDataWidth=data_width*number_of_components*samples_per_clock. The three values correspond to Maximum Data Width, Number of Video Components and Samples Per Clock in GUI, respectively. Refer to Design Flow Steps for more information.
