Abstract
A video filter processes pixel data by storing multiple lines of pixel data in a memory buffer and computes a weighted average of the data using a plurality of multipliers and accumulators. The pixel data which, for example, may represent luminance and/or chrominance values is stored in the buffer in an interleaved fashion. Preferably multiple lines of pixel data is stored in a single buffer, thereby reducing the number of traces that would otherwise be required if a separate buffer was used for each line of pixel data.
