Hardware, Embedded Systems Remember PA Semi? The company has just released, as promised, its first chipset. "They are full 64-bit PPC, support virtualisation, and would do Alitvec but that name is copyrighted by Freescale. Instead they do 'VMA'. The three parts run at a max wattage of 25, 15 and 10W for the 2.0, 1.5 and 1.0GHz parts respectively, with typical wattage listed at 13, 8 and 6W. The individual cores are said to have a 7W max and 4W typical power consumption at 2.0GHz." PA Semi was one of the prime reasons why Ars's John 'Hannibal' Stokes doubted Apple's reasoning for the switch to Intel.

Motorola called it AltiVec, Apple called it the "Velocity Engine".

Moto/Freescale = Altivec
PA Semi = VMA
IBM = VMX

Apple used "Velocity Engine" not only because of trademarks but also because it's vendor neutral - which was neccesary when using both IBM and Moto/Freescale chips in different products.

The x86 camp at least has this in-line due to their cross-liscensing agreement. But it really is kind of wierd that the PPC consortium can't get their members to agree on one name - or at least provide for an official vendor-nuetral term free to use for all its members.

Not really. Whether it's because they've not cross-licenced the names or not (and presumably they haven't) several features of x86 chips differ between AMD and Intel - such as 3DNow! and MMX, the No eXecute bit (which has a different name on Intel x86), and the two commands which send the new x86 processors into "fully-virtualizable" mode.
