This article

http://www.intel.com/technology/magazine/communications/slicing-by-8-0306.htm

seems to imply it's provided "free". It doesn't say anything about
being free of patents though.

The Sourceforge project referred to in the article (but for which no
link is given) seems to be this one:

http://sourceforge.net/projects/slicing-by-8

The "files" section contains a zip archive, inside which there are three
source files all of which state that the package, which is (c) Intel
Corp. 2004-2006, is released under the BSD license, with this URL:

http://www.opensource.org/licenses/bsd-license.html

Again, no mention of patents anywhere.
