sure, but I'm a bit confused -- there is a tiny amount of memory 
involved in the accumulator -- isn't it a single number?

(or, for doing it along an axis, at least it's one order of magnitude 
fewer numbers)

And with a double precision floating point unit, is the math any slower? 
would you have to push any more memory around?
