ABSTRACT:
An interpolation circuit multiplexes inputs prior to one or more additions during an interpolation operation, thereby reducing the number of components implementing the interpolation circuit. The multiplexers apply shifted inputs to adders in a sequence that produces the desired binary based interpolated values. The interpolation circuit can be used to programmably produce filter coefficients.
