    I have been involved in this field for some time and authored the GOSPL
system (Graphic Oriented Signal Processing Language) which appeared at the
same time as the BDC (Block Diagram Compiler) of Lincoln Labs and has now been
eclipsed by the Gabriel system of Berkeley.  In summary, my impression is that
exact mapping of algorithms into fixed point implementations has been relegated
to technicians in real companies and that academia consistently uses floating
point to bury this problem during algorithm development.

    I think you have an interesting problem.  Go for it.
