I've been looking into the AltiVec implementation. product() should run in
about 125 clock cycles (plus call overhead) if the branch folding magic of
the PPC works and I can get everything to schedule right. I'm looking at
invert() now.
What is the expected completion time for the project and is there a
followup project that will be able to use the same code base? I wouldn't
want to spend too much time optimizing the code if the project will be over
before I'm done.
