4. Video and Vision Processing IP Interfaces

The IPs have a main clock, an optional control clock, and some IPs have an optional memory interface clock..
Table 6.   Intel FPGA video stream input interface
Signal name Direction AXI4-Stream Wire Signal Width
axi4s_vid_in_tdata Input TDATA Number of data bytes * 8
axi4s_vid_in_tlast Input TLAST 1
axi4s_vid_in_tuser Input TUSER Number of data bytes
axi4s_vid_in_tvalid Input TVALID 1
axi4s_vid_in_tready Output TREADY 1
Table 7.   Intel FPGA video stream output interface
Signal name Direction AXI4-Stream Wire Signal Width
axi4s_vid_out_tdata Output TDATA Number of data bytes * 8
axi4s_vid_out_tlast Output TLAST 1
axi4s_vid_out_tuser Output TUSER Number of data bytes
axi4s_vid_out_tvalid Output TVALID 1
axi4s_vid_out_tready Input TREADY 1

Number of data bytes = max(2, ceil(bits per sample * number of color planes / 8) * pixels in parallel)
