The Dadda multiplier is a hardware binary multiplier design invented by computer scientist Luigi Dadda in 1965. It uses a selection of full and half adders to sum the partial products in stages (the Dadda tree or Dadda reduction) until two numbers are left. The design is similar to the Wallace multiplier, but the … See more To achieve a more optimal final product, the structure of the reduction process is governed by slightly more complex rules than in Wallace multipliers. The progression of the reduction is controlled by a … See more The example in the adjacent image illustrates the reduction of an 8 × 8 multiplier, explained here.
