- 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/jpegDec
- 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_u50_gen3x16_xdma_201920_3
- Run kernel(Step 3)
To get the benchmark results, please run the following command.
./build_dir.hw.xilinx_u50_gen3x16_xdma_201920_3/host.exe -xclbin build_dir.hw.xilinx_u50_gen3x16_xdma_201920_3/jpegDecoder.xclbin -JPEGFile t0.jpg
JPEG Decoder Input Arguments:
Usage: host.exe -[-xclbin -JPEGFile] -xclbin: the kernel name -JPEGFile: the path point to input *.jpg
Note: Default arguments are set in Makefile, you can use other pictures listed in the table.
