Abstract
A digital multiplier for multiplying a plurality of multiplicand signals X -X representing a multiplicand and a plurality of multiplier signals Y -Y representing a multiplier. In it, a plurality of intermediate results signals, such as partial product signals, are generated from the multiplicand signals and the multiplier signals. A plurality of adder circuits are also provided for adding the intermediate results signals to generate a plurality of final result signals representing the result of multiplying the multiplicand and the multiplier, wherein at least some of the adder circuits receive first signals representing intermediate addition results from at least two prior adder stages and also receive second signals representing intermediate results generated as the result of only a single addition. Finally, a plurality of delay elements are placed in selected second signal lines so as to delay the arrival of the second signals to the at least some of the adder circuits so as to synchronize the arrival of the inputs to the at least some of the adder circuits.
