Abstract:
In this paper, a novel method for designing reconfigurable Newton structure is proposed. The Newton structure is a variable fractional delay filter that implements Lagrange interpolation only. This structure has been extended later in the literature to implement other types of interpolation, such as Spline and Hermite interpolations. Our proposed method develops dynamically reconfigurable Newton structures that allow implementing different interpolation methods using the same fixed hardware implementation. This method allows reconfigurability through one input variable. Moreover, we present two sample rate conversion examples where we show how our method allows adapting the interpolation method to the processed signal, maximizing thereby the filtering performance.
