class
ieee754.part_mux.part_mux.PartitionedMux(width, partition_points)¶ Bases:
nmigen.hdl.ir.ElaboratablePartitionedMux: Partitioned “Mux”
takes a partition point set, subdivides a and b into blocks and “selects” them. the assumption is that “sel” has had its LSB propagated up throughout the entire partition, and consequently the incoming selector (sel) can completely ignore what the actual partition bits are.
