    Ok... So maybe IBM isn't interested in putting Altivec instructions in their PowerPCs.

    But tell me, what would stop Motorola or another Altivec licensee from creating a co-processor that handles Altivec instructions?

    Could we be looking at IBM G5s with a Motorola (or other party) Altivec unit?

    Re: Altivec co-processor?

    IBM can't put "AltiVec" in its PowerPCs because AltiVec is a Motorola trademark. They could instead design their own AltiVec-compatible vector processor and call it something else. A 4x32-bit PPC vector processor is a 4x32-bit PPC vector processor. A standalone AltiVec chip would be possible, but not likely (in my opinion) - the trend in computer logic has been consolidation of components, not fragmentation.

    Because that would clog the already satured system bus. Unless Altivec is on the processor running at full speed, Altivec would provide very little in terms of performance gain, and would fill the system bus much more quickly.

    It is a good idea though, especially if Apple moved over to IBM processors that lacked an Altivec alternative.
