This is complicated! It is necessary to compute a full NxN matrix of partial multiplication results, then perform a cascade of adds (long multipication, in binary), using PartitionedAdd, which will "automatically" break the results down into segments, at all times, keeping each partitioned result separate.
The [Wallace Tree](https://en.wikipedia.org/wiki/Wallace_tree) algorithm is presently deployed, here: we need to use the (more efficient) [Dadda algorithm](https://en.wikipedia.org/wiki/Dadda_multiplier)
