1D Conv

hls4ml.backends.quartus.passes.convolution_winograd module

class hls4ml.backends.quartus.passes.convolution_winograd.ApplyWinogradKernelTransformation

Bases: OptimizerPass

Transforms the weights of a Conv2D kernel to a format suitable for Wingorad convolution For further information, refer to Lavin & Gray, 2015 - Fast Algorithms for Convolutional Neural Networks

match(node)

Predicate to match on a given node.

Parameters:

node (Layer) – Node in the model graph to try matching the optimizer on.

transform(model, node)

Transformation to apply if matching was successful.

Transform should return a boolean value indicating if the model graph was altered (by adding/removing nodes).

Parameters:

  • model (ModelGraph) – Model to optimize

  • node (Layer) – The matched node in the model graph.
