Abstract
A method and system are provided for efficiently implementing a dual finite impulse response (FIR) filter to vertically filter video data. A unique feedback mechanism enables multi-filter performance while implementing fewer actual filters and accompanying line delays than required in the available art. Advantageous placement of arithmetic elements is used to compensate for approximation error introduced by the feedback mechanism, resulting in substantially undiminished circuit performance in a more efficient circuit than currently available.
