Here is also some Matlab based toolbox, I used
http://users.ece.utexas.edu/~bevans/...ter/index.html
.. Not very usefull for me, because it didnt convert automaticly / and
sqrt, and so I also started manual transformation.

From Washington came the Precise Framework, look for it here:
http://fsweb.olin.edu/%7Emchang/publ...ssertation.pdf

And if I remember right, there was a chapter about word length
optimization in a book from some of
the Lononder Imperial College (...some google-seconds later...):
George Constantinides, Peter Cheung und Wayne Luk
"Synthesis and Optimization of DSP Algorithms"
