In this paper, we propose low-power filtering algorithm developed via the sofl DSP framework. Soft DSP refers to scaling the supply voltage of a DSP implementation beyond the voltage required to match its critical path delay to the throughput. This deliberate introduction of input-dependent errors leads to degradation in the algorithmic performance, which is then compensated for via algorithmic error-control schemes. The proposed error-control schemes, based on forwardbackward linear prediction… CONTINUE READING
