on a three-stage pipelined multiplier/accumulator.

P
For a polynomial of degree N, the number of steps is [log 2 N + 1] and the
number of multiplier/accumulator units is (N + 1)/2.
The operations can also be scheduled on a pipelined multiplier/accumulator.
For instance, a scheduling for a three-stage unit is shown in Figure 10.3. In this
unit, Stages 1 and 2 perform partial product reductions, producing a redundant
product, and Stage ...
