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.
| Signal Name | Direction | Width | Description |
|---|---|---|---|
| s_axis_video_tdata | I | (data_width * samples_per_clock +7) /8*8 | Input Video Data |
| s_axis_video_tvalid | I | 1 | Input Video Valid Signal |
