The following table describes the AXI4-Stream signal names and descriptions.

Important: In the following table, 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 the IDE respectively. Refer to Design Flow Steps for more information.
