Default Video System Reference Design
With the HDL Coder™ software, you can generate an HDL IP core with AXI4-Stream Video
interfaces. You can integrate the HDL IP core into the
system reference design platform. The reference design supports
high-speed image processing and video streaming applications.
The reference design contains the IP blocks to handle HDMI input and output video interfaces. HDL Coder generates the HDL DUT IP core with an AXI4-Stream Video interface, and inserts it into the reference design. The AXI4-Stream Video interface processes the video stream from the HDMI Input IP, and sends the output video stream to the HDMI Output IP. The input stream to the HDL IP core is in RGB format. The reference design contains IP blocks that convert the video stream data between the YCbCr and RGB formats.
For parameter tuning, the IP core can have an AXI4-Lite interface that connects to the ARM processor.

Targeting the Reference Design
To target your video algorithm in Simulink® to the
Default video system reference design:
Model your video algorithm with the streaming pixel protocol. To generate an IP core with AXI4-Stream Video interfaces, in your DUT interface, implement the Pixel Data and Pixel Control Bus signals. You can optionally model the backpressure signal, Ready, and map it to the AXI4-Stream Video interface.
For more information, see Model Design for AXI4-Stream Video Interface Generation.
IP Core Generationas target workflow. Open the HDL Workflow Advisor. In the Set Target Device and Synthesis Tool task, specify
IP Core Generationas the Target workflow. For Target platform, choose from one of the boards listed in Board Support.
Default video systemas target reference design. In the Set Target Reference Design task, for Reference design, specify
Default video system (requires HDMI FMC Module). You can also specify whether the code generator inserts the AXI manager IP and the data capture IP for the JTAG or Ethernet connection into the reference design.
AXI manager and FPGA data capture in the HDL Workflow Advisor support programmable logic (PL) Ethernet only. The processing system (PS) Ethernet is not supported.
By default, the
Ethernetoption for the Insert AXI Manager (HDL Verifier required) and FPGA Data Capture (HDL Verifier required) parameters is available for the Artix®-7 35T Arty, Kintex®-7 KC705, and Virtex®-7 VC707 boards. To enable this option for other Xilinx boards that have the Ethernet physical layer (PHY), manually add the Ethernet media access controller (MAC) Hub IP in the
plugin_boardfile using the
addEthernetMACInterfacemethod before you launch the HDL Workflow Advisor tool.
For an example of automatic insertion of the AXI manager IP for the JTAG connection into a reference design, see Use JTAG AXI Manager to Control HDL Coder Generated IP Core.
Go through the workflow to generate the HDL IP core, and integrate the IP core
