Add to ORKGMost of the digital signal processing applications are implemented in embedded systems which are based on fixed-point arithmetic. The reduction of the time-to-market requires the automation of the fixed-point specification determination. The accuracy evaluation is one of the most important stage of this process. In this paper, a new methodology for evaluating the quality of non-recursive and non-linear systems is presented. The fixed-point specification ac-curacy is automatically determined through the computation of the Signal-to-Quantization-Noise-Ratio (SQNR) expression. The theo-retical approach used for computing the output noise power is de-tailed and the methodology developed for automating the accuracy evaluation is presented. Then,...
