- Work Directory(Step 1)
The steps for library download and environment setup can be found in l2_vitis_codec. For getting the design,
cd L2/demos/pikEnc
- 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.
make run TARGET=hw PLATFORM=xilinx_u200_xdma_201830_2
- Run kernel(Step 3)
To get the benchmark results, please run the following command.
./build_dir.hw.xilinx_u200_xdma_201830_2/host.exe --xclbin build_dir.hw.xilinx_u200_xdma_201830_2/pikEnc.xclbin PNGFilePath PIKFilePath --fast
PIK Encoder Input Arguments:
Usage: host.exe -[-xclbin] --xclbin: the kernel name --fast: the encoding mode PNGFilePath: the path to the input *.PNG PIKFilePath: the path to the output *.pik
Note: Default arguments are set in Makefile, you can use other pictures listed in the table.
