Method Detail

swapAssignment

public void swapAssignment()

Description copied from class: NoSWPipeLayout

Called by perturbConfiguration() to perturb the configuration. perturbConfiguration() decides if we should keep the new assignment. The assignment should contain only FilterSliceNodes when this is called.

Overrides:

swapAssignment in class NoSWPipeLayout<CellPU,CellChip>

initialPlacement

public void initialPlacement()

Description copied from class: NoSWPipeLayout

Random initial assignment.

Overrides:

initialPlacement in class NoSWPipeLayout<CellPU,CellChip>
