An essential step in embedded software development, floating- to fixed-point conversion can be tedious, labor-intensive, and error-prone. System engineers frequently design algorithms in floating-point math, usually double-precision. This format represents the ideal algorithm behavior but takes little account of the algorithmd-deOaos final realization in production software and hardware. Software engineers and suppliers in mass production environments often need to convert these algorithms to fixed-point math for their integer-only hardware. As a result, multiple iterations between system and software engineers are often required.Using a fault-tolerant fuel system model as an example, this article describes tools and a workflow for converting models from floating point to fixed point for production code generation. The approach described here uses two tools in Simulink Fixed Pointd-OC?D?: Fixed-Point Advisor and Fixed-Point Tool.By Bill Chou and Tom Erkkinen, The MathWorksThis article was published in MATLAB Digest, November 2008, which you can read at http://www.mathworks.com/company/newsletters/?s_cid=nws_flex
