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 GUI, respectively. Refer to Design Flow Steps
for more information.
