2.5.2.10. Parameter Group: input_stream_interface

Enable and configure the width of the input AXI4-Stream interface. If enabled, input streaming requires that the layout transform is also enabled. Neural network graphs compiled with an input streaming-enabled architecture cannot be sliced in the input layer, therefore the stream buffer depth must be large enough to fit the input layer.

Parameter: input_stream_interface/enable

Enables the input streaming module. Enable_layout_transform must also be true, and the transform must be configured for the target neural network graph.

Legal values:
true, false

Parameter: input_stream_interface/data_width

Sets the width of the AXI4-streaming input bus in bits.

Legal values:
2 n where n is 4 or greater.
For example, an architecture with a 128-bit input AXI streaming interface would include the following options:
input_stream_interface {
 enable: true
 data_width: 128
}
