- Work Directory(Step 1)
The steps for library download and environment setup can be found in README of L2 folder. For getting the design,
cd L2/examples/lkdensepyrof
- Build kernel(Step 2)
Run the following make command to build your XCLBIN and host binary targeting a specific device. Please be noticed that this process will take a long time, maybe couple of hours.
export OPENCV_INCLUDE=< path-to-opencv-include-folder > export OPENCV_LIB=< path-to-opencv-lib-folder > export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:< path-to-opencv-lib-folder > export PLATFORM=< path-to-platform-directory >/< platform >.xpfm make host xclbin TARGET=hw
- Run kernel(Step 3)
To get the benchmark results, please run the following command.
make run TARGET=hw
- Example output(Step 4)
