Software

Kyungtae Han and Brian L. Evans, ``Floating-Point to Fixed-Point Transformation Toolbox,'' copyright 2005-2006 by The University of Texas. This freely distributable toolbox automates conversion of floating-point programs to fixed-point programs and quantifies the tradeoff in signal quality vs. implementation complexity in fixed-point wordlength choices. One application of this toolbox is to reduce the power consumed by existing algorithms in an embedded software or hardware implementation. Version 1.1 (May 22, 2006) is available at http://users.ece.utexas.edu/~bevans/projects/wordlength/converter/index.html
