Abstract :
DSP systems used in portable telecommunication applications normally exploit filtering functions implemented in software on core processors. In this paper, we explore, by means of realistic examples, the impact of different architectural choices, as well as core processor selection, on the power dissipated by IIR and FIR filtering routines.
