Circuit structure and system configuration for implementing pseudo four-point interpolation

摘要

The present invention discloses a data processing module for generating an interpolated output from four sampled input data. The data processing module includes an input means, i.e., a memory module, for receiving the four sampled input data. The data processing module further includes a pseudo four-point interpolation (PFPI) module for receiving a ratio value p and for generating the interpolated output by utilizing a novel pseudo four-point interpolation algorithm as represented by an Equation (6).
