Generate Custom Bitstream

To deploy a deep learning network to your custom target device, generate a custom bitstream by using the dlhdl.ProcessorConfig object.

  1. Create a dlhdl.ProcessorConfig object.

    hPC = dlhdl.ProcessorConfig;

  2. Set up the tool path to your design tool. For example, to set up the path to the Vivado® design tool, enter:

    hdlsetuptoolpath('ToolName','Xilinx Vivado','ToolPath','C:\Xilinx\Vivado\2020.2\bin\vivado.bat');
  3. Generate the custom bitstream.


  4. Locate the bitstream file and associated MAT file at cwd\dlhdl_prj\, where cwd is your current working folder. The name of the bitstream file is dlprocessor.bit . The name of the MAT file is dlprocessor.mat.

    To use the generated bitstream for the supported Xilinx® boards, copy the dlprocessor.bit and dlprocessor.mat files to the present working folder.

    Xilinx custom bitstream files

    To use the generated bitstream for the supported Intel® boards, copy the dlprocessor.core.rbf, dlprocessor.mat, dlprocessor.periph.rbf, and dlprocessor.sof files to the same present working folder.

  5. Deploy the custom bitstream and deep learning network to your target device.

    hTarget = dlhdl.Target('Xilinx');
    net = resnet18;
    hW = dlhdl.Workflow('Network',net,'Bitstream','dlprocessor.bit','Target',hTarget);
    % If your custom bitstream files are in a different folder, use:
    % hW = dlhdl.Workflow('Network',snet,'Bitstream',...
    % 'C:\yourfolder\dlprocessor.bit','Target',hTarget);
