Web(wider) adder… however, we can consider cascading four of the 4-bit fast-carry adders to implement a 16-bit adder. To do this, we must consider the carry bits that must be generated for each of the 4-bit adders. We can adapt the approach used above to create a higher-level fast-carry logic unit to generate those carry bits quickly as well.
