- AMD K9
The AMD K9 represents a microarchitecture by
AMD designed to replace the K8 processors, featuring dual-core processing.Development
K9 appears originally to have been an ambitious 8 issue per clock cycle core redesign of the K7 or the K8 processor core. [ [http://www.theinquirer.net/default.aspx?article=27421 The Inquirer report, 3 November 2005] ] At one point, K9 was the "Greyhound" project at AMD, and was worked on by the K7 design team beginning in early 2001, with tape-out revision A0 scheduled for 2003. The L1 instruction cache was said to hold decoded instructions, essentially the same as Intel's trace cache.
The existence of a massively parallel CPU design concept for heavily multi threaded applications has also been revealed, as a planned successor to K8. This was reportedly canceled in the conceptualization phase, after about 6 months' work. [ [http://www.anandtech.com/cpuchipsets/showdoc.aspx?i=2986&p=5 Anandtech, May 11th, 2007] ]
At one time K9 was the internal codename for the dual-core
AMD64 processors as the brandAthlon 64 X2 , [ [http://www.theinquirer.net/default.aspx?article=37444 The Inquirer report, 6 February 2007] ] [ [http://www.syndrome-oc.net/articles.php?article=94&lang=en Video interview of Giuseppe Amato (AMD's Technical Director, Sales and Marketing EMEA) done in February 2007] ] however AMD has distanced itself from the old K series naming convention, and now seeks to talk about a portfolio of products, tailored to different markets.
