<p>A multi-staged image processing pipeline (410) in a page printer (10) includes a splitter stage (425) for splitting a scan line of print data into sections for improved formatting efficiency and speed in the pipeline. In a preferred embodiment, the splitter stage forces a section of the scan line data to be processed by all relevant image processing stages (430,435,440,445,450) with reduced cache thrashing. Each section of scan line data is set to be of a size that is optimal for (i.e., not greater than) the cache memory (25) available. Advantageously, the splitter provides dynamically configurable splitter sizing and enables each stage to work on the data that is currently in the cache. <IMAGE></p> |
