The following table shows the AXI4-Lite
control interface signals. This interface runs at the aclk_ctrl
clock. Control of the video processing pipe is only supported through
the Video Processing Subsystem driver. Data-width is automatically configured based on the
PPC of the design.
Note: Control of the video processing pipe is only supported through the video
processing subsystem driver. The register map is provided for debug purposes only.
Note: AXI write and read data_width selection is compatible to the part
selected.
For example : KU+ can support only up to 64 bits and ZU+/Versal supports up to 128 bits.
