Estimate Performance of Deep Learning Network by Using Custom Processor Configuration

  1. Create a custom processor configuration object of class dlhdl.ProcessorConfig.

  2. Create an object of class workflow by using the dlhdl.Workflow class.

  3. Set the deep learning network and processor configuration for the workflow object.

  4. Call the estimate function for the workflow object.

    The speed and latency is stored in a structure struct and displayed on the screen.

For example:

hPC = dlhdl.ProcessorConfig;
snet = vgg19;
hW = dlhdl.Workflow('Network', snet, 'ProcessorConfig',hPC);
result = hW.estimate('Performance');

The result of the estimation is:
