Input Arguments

expand all

Deep learning network deployment options, specified as adlhdl.Workflow object.

Output Arguments

expand all

Bitstream resource utilization returned as a structure.

• The Block Memory Bits utilization is available for Intel® bitstreams only.
• The resource utilization results of Intel bitstreams show the Block RAM utilization as 100%. To analyze bitstream resource utilization, refer to the Block Memory Bits utilization instead.

1. Create a file in your current working folder calledgetLogoNetwork.m. In the file, enter:
   function net = getLogoNetwork
   if ~isfile('LogoNet.mat')
   url = 'https://www.mathworks.com/supportfiles/gpucoder/cnn_models/logo_detection/LogoNet.mat';
   websave('LogoNet.mat',url);
   end
   data = load('LogoNet.mat');
   net = data.convnet;
   end
2. Create a dlhdl.Workflow object that hasLogoNet as the Network argument andarria10soc_single as the Bitstream argument.
   snet = getLogoNetwork;
   hW = dlhdl.Workflow('Network',snet,'Bitstream','arria10soc_single');
3. Call getBuildInfo argument to retrieve thearria10soc_single resource utilization. Store the resource utilization in area.
