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. -- Alvaro Herrera http://www.CommandPrompt.com/ The PostgreSQL Company - Command Prompt, Inc. ---------------------------(end of broadcast)--------------------------- TIP 3: Have you checked our extensive FAQ? http://www.postgresql.org/docs/faq
