Intel FPGA streaming video interfaces The IP has are up to eight video streaming input interfaces, one for each enabled mixer layer. In the signal names, x represents the layer number. 0 is the base layer.

axi4s_vid_x_in_tdata In AXI4-S data in.
axi4s_vid_x _in_tvalid In 1 AXI4-S data valid.
axi4s_vid_x _in_tuser In

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_x_in_tlast In 1 AXI4-S end of packet.
axi4s_vid_x _in_treadyout 1 1 AXI4-S data ready.
axi4s_vid_out_tdata Out 39 AXI4-S data in.
axi4s_vid_out_tvalid Out 1 AXI4-S data valid.
axi4s_vid_in_tuser Out 40

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.
axi4s_vid_out_tready In 1 AXI4-S data ready.

The equation gives all tuser widths in these interfaces:

N = ceil (tdata width / 8)

39

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)

40

The equation gives all tuser widths in these interfaces:

N = ceil (tdata width / 8)
