adders). The number of bit slices in online units is reduced as discussed on
page 526. Moreover, the modules are interconnected serially. The parallel

outputs are converted to parallel form using on-the-fly conversion and
multiplexed to obtain the filter output.
This example indicates that significant speedups might be possible using the
online alternative.
