2.5.2.5. Parameter Group: depthwise

This parameter group configures the depthwise module. The depthwise module accelerates the depthwise convolutions.

If a depthwise layer has more parameters than the depthwise module can support, the layer is executed on the general PE array.

Parameter: depthwise/K_vector

This parameter controls the width of the depthwise interface. Typically, the architecture optimizer is used to set this parameter.

Legal Values:
[16, 32, 64]

Parameters: depthwise/max_window_height, depthwise/max_window_width

These parameters set the maximum window height and width that the architecture can support. Typically, you set this value to the size of the largest max depthwise window in your graph.

Larger values cost more FPGA area.

Legal Values:
[3, 5, 7]

Parameters: depthwise/max_stride_vertical, depthwise/max_stride_horizontal

These parameters set the maximum stride values that the architecture can support. Typically, you set these to the largest value your graph requires after a depthwise convolution.

Larger values cost FPGA area.

Legal Values:
[1-4]

Parameters: depthwise/max_dilation_vertical, depthwise/max_dilation_horizontal

These parameters set the maximum dilation values that the architecture can support. Typically, you set these to the largest value your depthwise convolutions in your graph require

Larger values cost FPGA area.

Legal Values:
[1-6]
