Descripción
For the digital signal processing (DSP) part of mixed-signal systems, fixed-point arith-metic is favoured due to its high efficiency in terms of implementation cost, namely energyconsumption, area, and latency. Fixed-point arithmetic provides low-cost operators at theexpense of an unavoidable error between the ideal precision values and the finite precisionones. With a careful data word-length optimisation process, the designer can safely profitfrom the inherent trade-off between implementation cost and computation accuracy. Inthis chapter, we describe in detail the different stages comprising the fixed-point con-version process (i.e., dynamic range evaluation, word-length optimisation, and accuracyevaluation) and propose practical solutions to address each stage.
