The Zynq UltraScale+ MPSoC Base Targeted Reference Design (TRD) is an embedded video processing application running on a combination of APU (SMP Linux), RPU (bare-metal) and PL.
The design supports the following video interfaces:
- Virtual video device (vivid) implemented purely in software
- USB webcam connected to the PS (optional)
- Test pattern generator (TPG) implemented in the PL
- HDMI Rx capture pipeline implemented in the PL
- MIPI CSI-2 Rx based image sensor pipeline implemented in PL + FMC
- DP Tx display pipeline in the PS
- HDMI Tx display pipeline implemented in the PL
The following processing accelerators are implemented as memory-to-memory pipelines in the PL:
- 2D-Convolution filter with programmable coefficients
- Dense optical flow algorithm
The TRD demonstrates the value of offloading computation intensive tasks from the PS onto PL, thereby freeing APU resources. The APU load is plotted on the GUI to compare a pure software vs hardware accelerated implementation.
The RPU is used to monitor the live memory throughput of the design by reading the built-in AXI performance monitors (APM) inside the PS. The data is sent to the APU via the OpenAMP communication framework and plotted on the GUI.

4 Design Files
4.1 Design Modules
The reference design is split into 10 design modules DM1 to DM10:
- DM1 – APU SMP Linux
- DM2 – RPU0 FreeRTOS Application
- DM3 – RPU1 Bare-metal Application
- DM4 – APU/RPU1 Inter Process Communication
- DM5 – APU Qt Application
- DM6 – PL Video Capture

- DM10 – Full-fledged Base TRD
Each module is described in more detail on the respective tutorial page (see below).
The following table shows the dependency matrix between different modules. For example: DM6 (row) depends on or builds on top of modules DM1 and DM5 (columns).
4.2 Design Components
The top-level directory structure shows the the major design components organized by execution unit (APU, RPU0, RPU1). A pre-built SD card image is provide for DM10 along with a basic README and legal notice file.
The below figure shows the relevant design components for DM10 as well as inter-dependencies and generated output products.
The below table shows which design components are used in which design modules. A graphical view for each design module is provided on the respective design module tutorial page.
|Design Component||Design Module|
5.1 Board SetupRequired:
- Connect power supply to 12V power connector.
- Connect USB mouse via USB hub to the USB3 micro-AB connector.
Note: Certain monitors have multiple HDMI ports supporting different HDMI standards. Make sure you choose an HDMI 2.0 capable port (if available) for 4k60 performance
- Connect a DisplayPort cable to DisplayPort connector on the board; connect the other end to a monitor OR
- Connect an HDMI cable to HDMI Tx connector (top) on the board; connect the other end to a monitor
Note: Make sure you only connect either DP or HDMI Tx on the board, not both, otherwise the design might malfunction
- Connect micro-USB cable to the USB-UART connector; use the following settings for your terminal emulator:
- Baud Rate: 115200
- Data: 8 bit
- Parity: None
- Stop: 1 bit
- Flow Control: None
- Insert SD card (FAT formatted) with binaries copied from $TRD_HOME/images/dm10 directory.
Jumpers & Switches:
- Connect a USB webcam to the USB hub.
Note: The USB webcam needs to output YUYV pixel format. Other formats are not supported in this design.
- Connect an HDMI cable to HDMI Rx connector (bottom) on the board; connect the other end to an HDMI source
- Connect the LI-IMX274MIPI-FMC module to the HPC0 FMC connector on the board
Note: The design only supports this FMC on rev 1.0 boards. Vadj needs to be set to 1.2V for correct operation of the daughter card. If the FMC card does not seem functional, please follow the instructions explained in Answer Record AR67308 to check and/or set Vadj.
- Set boot mode to SD card:
- Rev 1.0: SW6[4:1] - off,off,off, on
- Rev D2: SW6[4:1] - on, off on, off
- Configure USB jumpers for host mode
- J110: 2-3
- J109: 1-2
- J112: 2-3
- J7: 1-2
- J113: 1-2

5.2 Build and Run Flow
The following tutorials assume that the $TRD_HOME environment variable has been set as below.
For rev 1.0 or rev D2 with production silicon:
For rev 1.0 with ES2 silicon:
For some modules, the $PETALINUX environment variables needs to be set as well. This is done automatically when you source the PetaLinux settings.sh script (see PetaLinux installation guide).
For the individual tutorials, follow the links below:
6 Other Information
6.1 Known Issues
- Accelerator frame rate drops if HDMI Tx 4K60 is selected. The Filter2d frame rate maxes out at 4K 30 fps and the optical flow frame rate maxes out at 4K 35 fps
- Frequency: Always
- Workaround: None
- VPSS scaler in HDMI pipeline behaves incorrectly when switching between resolutions
- Frequency: Common
- Workaround: Reboot the board and select target resolution with -r switch on first invocation of application
- The perfapm-server module has been modified to use the 2017.2 version of the standalone BSP. The 2017.4 BSP version results in a hang in the OpenAMP communication with the GUI which causes the GUI to lock-up.
- Frequency: N/A
- Workaround: The provided perfapm-server application is based on the 2017.2 standalone BSP which doesn't expose this issue.
- SDSoC accelerator code runs very slow in pure software implementation when Debug configuration is used. For faster execution, set project build configuration to Release which sets SDSoC compiler to optimize most (-O3).
- The application only supports the following display resolutions: 3840x2160, 1920x1080 and 1280x720.
- The application does not support audio.
- USB webcams:
- Need to support the YUYV pixel format.
- Most webcams don't support resolutions > 1080p using uncompressed video. Make sure you start the GUI in 1080p or 720p mode using the -r switch if you want to use your webcam as video source.
- For USB2 webcams, it is expected to see increased latency and low frame rate.
- Do not connect a DisplayPort cable and HDMI Tx at the same time.
- Make sure the DisplayPort or HDMI Tx cable is plugged in when you power on the board.
- DP-to-HDMI adapters are not supported, see AR 67462
- HDMI Rx:
- Does not support YUV 4:2:0 input.
- Does not support HDCP encrypted input.
- Does not support hotplug or dynamic resolution changes while the application is running.
- Leopard LI-IMX274MIPI-FMC:
- The Leopard IMX274 MIPI FMC is only supported on rev 1.0 boards and will not work on rev D2 boards.
- SDSoC does not support “Estimate Performance” for the xfopenCV library and in general for all the C++ templates (the part of Performance Estimation flow not yet supported is the estimate of software performance for function templates). Once the HLS estimate of HW resources pops up, the Ethernet P2P communication process between the SDSoC GUI and the board stalls forever and no error message is displayed.
