  1. It would be interesting to know how they implemented 4-bit multiplication. One could do it as a pure table lookup (there are only 256 possible results) but it's hard to tell if it's faster to do the full multiplication calculation in hardware instead. With the huge amount of transistors the new chips have, it might be faster to always compute everything on the fly.
