- Actually, they do give a reason:
-
- http://www.autopd.com/ax_multiplier.html
-
- It says that they have a logarithmic-type compression tree structure,
- but that has only nearest-neighbor connections (typically,
- wallace-tree and such have very irregular layout). The resulting
- short wires and low capacitance is what gives them their claimed
- 50%-100% speedup.
-
- Now whether it is true or just reinvented a wheel, time will tell...
