Digital signal processing applications are specified in floating-point in order to prevent problems due to computing precision. However, in order to satisfy cost constraints, application implementation in embedded systems requires fixed point arithmetic using. Thus, the application defined in floating point arithmetic must be converted into a fixed-point specification. To reduce applications time-to-market, tools to automate floating-point to fixed-point conversion are needed. In these outils, an important stage corresponds to precision evaluation of fixed-point specification. Indeed, fixed-point arithmetic generates noise sources due to the elimination of some bits while a format change. These noises propagates through the system and modif...
