Pass the only weight-1 wire through, output: 1 weight-1 wire
Pass the two weight-2 wires through, outputs: 2 weight-2 wires
Add a full adder for weight 4, outputs: 1 weight-4 wire, 1 weight-8 wire
Add a full adder for weight 8, and pass the remaining wire through, outputs: 2 weight-8 wires, 1 weight-16 wire
Add a full adder for weight 16, outputs: 1 weight-16 wire, 1 weight-32 wire
Pass the two weight-32 wires through, outputs: 2 weight-32 wires …
