Abstract

The purpose of this work is to show the advantages of implementing digital signal processing for high quality audio applications in custom floating-point. We consider the trade-offs dynamic range vs. precision (i.e., quantization) by comparing standard floating-point (namely, binary32) to custom floatingpoint. Moreover, by resorting to Tunable Floating-Point (TFP) hardware units, we can adjust the dynamic range and the precision in different parts of the algorithms to explore several alternatives. Results show that 16-bit floating-point formats can give a good compromise between quality and energy efficiency.
