In one embodiment, a configurable device is provided for multiplying a
plurality of digital words with a corresponding plurality of
coefficients. The configurable digital filter includes: a plurality of
lookup tables, each lookup table corresponding to at least one of the
coefficients and operable to receive at least a portion of a
corresponding at least one of the digital words, each lookup table
configured multiples of the corresponding at least one coefficient such
that the lookup table is operable to retrieve an entry to provide an
output equaling a multiplication of the portion with the corresponding at
least one coefficient.
