The AXI4-Stream Remapper core has two register configurable values namely,
inPixClk and outPixClk, which specify the PPC on the input and
the PPC required on output respectively. These values are used by the IP core for remapping
between various PPCs.
For all PPC values, the first pixel is aligned to the lower significant part of
the video AXI4-Stream
TDATA. For example, when the PPC value is 4
vid_in_axis_tdata/vid_out_axis_tdata = {pixel3, pixel2, pixel1, pixel0}
