Intel FPGA streaming video interfaces

axi4s_vid_in_tdata In AXI4-S data in.
axi4s_vid_in_tvalid In 1 AXI4-S data valid.
axi4s_vid_in_tuser In

AXI4-S tuser

tuser[0] indicates start of video frame when asserted

tuser[1] indicates the start of an image information, end of field or auxiliary control packet when asserted.

axi4s_vid_in_tlast In 1 AXI4-S end of packet.
axi4s_vid_in_tready Out 1 AXI4-S data ready.
axi4s_vid_out_tdata Out 41 AXI4-S data in,
axi4s_vid_out_tvalid Out 1 AXI4-S data valid,
axi4s_vid_in_tuser Out 42

AXI4-S tuser

tuser[0] indicates start of video frame when asserted

tuser[1] indicates the start of an image information, end of field or auxiliary control 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 tdata sizes in these interfaces:

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

42

The equation gives all tuser widths in these interfaces:

N = ceil (tdata width / 8)
