Statistical method for floatingpoint to fixedpoint conversion
, 2002
"... The algorithms used by communication, voice and image processing systems are typically specified as floating point operations. On the other hand, digital ASIC VLSI implementations of these algorithms rely on fixedpoint approximations to reduce cost of hardware while increasing throughput rates. The ..."

. The essential design step of floatingpoint to fixedpoint conversion (FFC) proves to be time consuming due to the nonlinear characteristics and the massive design optimization space. In the bid to achieve short product cycles, the execution of FFC is often left to hardware designers, who are familiar with VLSI
An automated floatingpoint to fixedpoint conversion methodology
 Proc. IEEE Int. Conf. on Acoust., Speech, and Signal Processing
, 2003
"... Most existing analyses of quantization effects are given under the condition that all decisionmaking blocks, if exist in a system, produce identical decisions in both fixedpoint and infiniteprecision (IP) implementations. However, in doing floatingpoint to fixedpoint conversion (FFC), a fixedp ..."

A FloatingPoint to FixedPoint Conversion Methodology for Audio Algorithms, technical report
, 2004
"... Most Digital Signal Processors perform computations on integers, or fixedpoint numbers, rather than floatingpoint numbers. In contrast, Digital Signal Processing algorithms are often designed with real numbers in mind and usually implemented in floatingpoint. Apart from finite wordlength effects ..."

Test Case Generation for Adequacy of Floatingpoint to Fixedpoint Conversion
"... Porting an application written for personal computer to embedded devices requires conversion of floatingpoint numbers and operations into fixedpoint ones. Testing the conversion hence requires the latter be as close as possible to the former. The closeness is orthogonal to code coverage and requir ..."
