Default Paper about selecting fixed point bit widths?

Hello all,

Can anyone point me to a good general purpose paper about selecting
appropriate bit-widths for a fixed point implementation of a signal
processing algorithm? I've looked around and haven't found anything
that describes a general methodology to use. I have implemented a
design and it isn't performing as well as I would like. I suspect it
has to do with some poor selection of bit slicing when it comes to
multipiers and accumulators.

Thanks for your help!
