Abstract

Embodiments herein describe a hardened fractional resampler that includes a fixed filter that supports simultaneous processing of N input samples with minimal additional combinational logic and no additional multipliers. In one embodiment, the fractional resampler is implemented in an integrated circuit using hardened circuit. The embodiments below exploit a pattern in the order filter phases in fractional resampling systems (such as a SSR resampling system) to use filter phases in a single fixed filter to process multiple input samples in parallel, where these filter phases would have been unused in previous resampling systems.
