Description of tools and a workflow for converting models from floating point to fixed point
|29 Jun 2009||Linda Webb||
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 algorithm’s 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.
