If values of "d" for "don't care" appear in the table, this adds flexibility during the reduction phase.

Because of this, Dadda multipliers have a less expensive reduction phase, but the numbers may be a few bits longer, thus requiring slightly bigger adders.

In 1995, the program entered into the definition and risk reduction phase, where it won two DOD awards for successful cost and technology management.

The Federal Government announced subsidies worth 1 billion Reais ( US$ 556 millions) so these prices will face a new reduction phase.

Originally, the weight reduction phase had included removing the anchors from the battleship, but Wallin ordered one of the anchors to be reattached.

The basic operation can be described as a sequence of four separate phases: the filling phase, the spill phase, the injection phase, and the pressure reduction phase.

Compared to a Wallace tree, which requires ten full adders and half adders, the reduction phase of the Dadda multiplier has the same delay, but requires only six.

Similarly, a set of 'reducers' can perform the reduction phase - provided all outputs of the map operation that share the same key are presented to the same reducer at the same time, or if the reduction function is associative.
