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:

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"
