The problem with these algorithms that tradoff one or more

give anything and often lose when both multiplies and
divides are emulated in software.
Actually on rereading this: is there really any Linux port
that emulates multiplies in software? I thought that was only
done on really small microcontrollers or smart cards; but anything
32bit+ that runs Linux should have hardware multiply, shouldn't it?
SPARC < v8 does multiplies using an MSTEP instruction.
