Abstract :
The concept of merged arithmetic is introduced and demonstrated in the context of multiterm multiplication/addition. The merged approach involves synthesizing a composite arithmetic function (such as an inner product) directly instead of decomposing the function into discrete multiplication and addition operations. This approach provides equivalent arithmetic throughput with lower implementation complexity than conventional fast multipliers and carry look-ahead adder trees.
