Does anyone have any idea how AVR and MSP430 compare in terms of floating
point and integer math? We need to do some computational number crunching
(preprocessing) in our devices but aren't sure which of the above to pick.

The MSP430 is 16 bits so it should be faster in math it seems to me, but are
there other aspects which are important? The computations are 'DSP like'
(lots of adding amd multiplication).
