KNI (nee MMX-2) details (from comp.sys.intel): ---------- From: Erik Corry <erik@arbat.com> Newsgroups: comp.sys.intel Subject: Katmai/MMX2 details released According to c't, Intel has released details of MMX2 in Katmai. heise.de (English link anyone?). The Katmai has 8 128-bit MMX2 registers usable as 4x32bit fp each. They are not aliased to the normal fp or MMX registers. This is a correct decistion IMHO, would have been better for MMX, too. It means the OS needs to know about the extra registers, but upgrading your OS is no big deal (if you are upgrading your processor), and if they do it right, the application cannot tell that MMX2 is there at all unless the OS activates the support, in which case it is reasonable to expect the OS to also handle saving and restoring the registers on context switches. (Not sure whether W95 will support it. Seems beyond doubt that W98 will, as will Linux for both 2.0 and 2.1/2.2). The advantage is that you can do MMX2 in parallel with MMX or fp work, and it probably simplifies the internal data paths. Did AMD get this one wrong for 3D-Now? There are conditional move commands, conversion functions for MMX and FP, memory-streaming (cache control), distance calculation and min-max commands. ---------- My comment: The new context-switching instructions were introduced in Deschutes (i.e. current PII) and are already used by Win98.

Paul, There is no end to the games these analysts play. Amen. It is really something. Kurlak continues to talk down Intel just before options expiration. It is amazing he can still kill an Intel rally. Dale
