A sample filtering system and method for concurrently filtering sample data for
two or more sequential pixels (in a scan-line) are disclosed. The system may include
a sample cache, a control register, a read cache controller, and a sample-to-pixel
calculation unit. The read cache controller reads a first set of S samples from
the sample cache, and outputs a second set of S samples to the sample-to-pixel
calculation unit. The second set of samples may have one or more subsets of samples,
with each subset of samples selected to cover the filter region for one of the
sequential pixels. The sample-to-pixel calculation unit may process each subset
separately and concurrently.
