Zynq UltraScale MPSoC Base TRD 2016.3 - Design Module 8
Return to the Design Tutorials Overview.Design Overview
This module shows how to move the 2D convolution filter from software to hardware using the PL optimized hls_video library that provides an OpenCV equivalent function.
Design Components
This module requires the following components:
- zcu102_base_trd (SDSoC)
- pmu_fw
- petalinux_bsp
- zynqmp_fsbl
- bl31
- u-boot
- kernel
- device tree
- rootfs
- filter2d (HW)
- video_lib
- video_qt2
Build Flow Tutorials
2D Filter Sample
This tutorial shows how to build the hls_video version of the 2D filter sample based on the Base TRD SDSoC platform.- Open the existing SDx workspace from design module 7 using the SDx tool.
% cd $TRD_HOME/apu/video_app % sdx -workspace . &&
- Expand the filter2d project and sources in the project explorer, select the filter2d_sds function and click 'Toggle HW/SW' to select this function for hardware acceleration.
- Verify the function was added to the HW functions in the project settings panel and the clock frequency is set to 300MHz
- Right-click the filter2d project and select 'Build Project'.
- Copy the content of the generated sd_card folder to the dm8 SD card directory
% cp -rf filter2d/Release/sd_card $TRD_HOME/images/dm8
Video Qt Application
There is no need to rebuild the video_qt2 application if you have already built it in module 7, otherwise follow the instructions from module 7.- Copy the generated video_qt2 executable to the dm8 SD card directory or alternatively use the pre-built version bundled with the SDSoC platform.
% cp -f video_qt2/video_qt2 $TRD_HOME/images/dm8/bin/
Run Flow Tutorial
- See here for board setup instructions.
- Copy all the files from the $TRD_HOME/images/dm8 SD card directory to a FAT formatted SD card.
- Power on the board to boot the images; make sure INIT_B, done and all power rail LEDs are lit green.
- After ~30 seconds, the display will turn on and the application will start automatically, targeting the max supported resolution of the monitor (one of 3840x2160 or 1920x1080 or 1280x720).
- Upon application exit, use the below login and password to log into the framebuffer or serial console:
root@Xilinx-ZCU102-2016_3 login: root password: root
- The SD card file system is mounted at /media/card
- To re-start the TRD application type run_video.sh
- The user can now control the application from the GUI's control bar (bottom) displayed on the monitor.
- By default, application launches with VIVID as a video-source, user can also select TPG from the "Video-source selection" button present on the GUI's control-bar.
- Virtual Video Device (VIVID): emulates a USB webcam purely in software
- USB Webcam (UVC): using the universal video class driver
- Test Pattern Generator (TPG); implemented in the PL
- A 2D convolution filter can be turned on and different filter presets can be selected; the following filter modes are available:
- OFF - accelerator is disabled/bypassed
- SW - accelerator is run on A53 using OpenCV algorithm
- HW - accelerator is run on PL generated from HLS algorithm
- The video info panel (top left) shows essential settings/statistics.
- The CPU utilization graph (top right) shows CPU load for each of the four A53 cores.
