The EE times (www.eet.com) reports:
Research by a team of U.K. mathematicians has produced a different
approach to two of the most fundamental aspects of electronic computation:
hardware addition and multiplication.
Can anyone tell me how to find the online version? I spent a few minutes
trying, but didn't get anywhere. I don't mind registering either.

news:LoI09.10863$[EMAIL PROTECTED]...
- I read in EE Times of July 22,2002, page 20, that there is a company in the
- UK that claims they have a ways of building full adders and 4:2 compressors
- that are much faster than those built using traditional approaches. They claim
- this enables them to implement multipliers that have 2x the speed of traditional
- multiplier approaches. Of course, no details are revealed. The company's web
- site is at www.autopd.com. I looked at it but no details are given either, as one
- might expect.
-
- 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...
