ABSTRACT:
An embodiment of the present invention is an apparatus to filter two-dimensional (2-D) data. A first filter processes two-dimensional (2-D) data in a block of pixels in a first dimension for a plurality of filter sizes. The block has a swath. A register file stores the 2-D data based on programmable information. A second filter filters the stored 2-D data in a second dimension to generate filter outputs in one of static and dynamic modes based on the programmable information. The static mode leaves the filter outputs fixed for the swath and the dynamic mode selects the filter outputs on a pixel basis. The filter outputs include first and second filter outputs.
