The performance of existing adders varies widely in their speed and area requirements, which in turn sometimes makes designers pay a high cost in area especially when the delay requirements exceeds the fastest speed of a specific adder, no matter how small the difference is. To expand the design space and manage delay/area tradeoffs, the authors propose new adder architecture and a design methodology. The proposed adder architecture, named heterogeneous adder, decomposes an adder into blocks (sub-adders) consisting of carry-propagate adders of different types and precision.
