axi4s_vid_in_tuser Out 8

AXI4-S tuser

tuser[0] indicates start of video frame when asserted

tuser[1] indicates the start of a non-video packet when asserted.

axi4s_vid_out_tlast Out 1 AXI4-S end of packet .

7

the equation gives all tdata widths in these interfaces:

max (ceil((bits per color sample x number of color planes x pixels in parallel) / 8) x 8, 16)

8

The equation gives all tuser widths in these interfaces are sized according to the equation

N = ceil (tdata width / 8)
