Ahhh, but at one time Macs did have DSP's on the motherboard and one
could add more with a Photoshop card. I had a Quadra 840av that would
run rings around even much later PowerPC's for functions that called on
the DSP chips. The Altivec is certainly an effort at making this speed
possible and perhaps one could argue that it is really no different.
You could optimize your code for built in DSP's or you could optimize
it for Altivec (if it can be done with vectors).

For the last few years I have been using an old turbo color
NeXTstation for this purpose - it has a built-in DSP and I have been
able to use it to control an experiment using the digital
inputs/outputs from the DSP and count photons (up to 1 MHz) using the
DSP. I am delighted with the performance of the NeXT (for an '040
machine) and ease of programming (in Obj. C) and want to upgrade to
one of my old beige and BW OSX boxes. Unfortunately, the Macs didn't
come with a DSP, so I need to add one (the NeXT also had DSP drivers
in the free MusicKit). (The alternative Labview approach to DAQ is
completely unacceptable to me, with its limitations on the Mac)
Yeah! Mathematica runs on my old good 25MHz pizza NeXT station faster
then on my 1GHz G4. If Steve & Co. are so crazy about music, I wonder
why they do not take the next obvious step and put DSP in every Mac.
... just dreaming...
