A good way to speed up neural net calculations is to use the multimedia
extensions (MMX, AltiVec, etc.) of modern CPUs.  Going to integer arith-
metic (as e.g. MMX requires) has its problems though in that the gradient
calculations must be quite precise for learning subtle, complex problems.
IMO this is opening a can of worms, and not worth it given that new CPUs
nowadays supply floating-point multimedia extensions.

Best,
