Abstract:
1. A method of performing parallel image processing, comprising: processing one or more graphical objects to generate a plurality of convex polygons; forming an edge list for representing each of the plurality of convex polygons; distributing the edge list to a plurality of scan line image processing units; processing the plurality of convex polygons described in the edge list in parallel using the plurality of scan line image processing units; synchronizing operations of the plurality of scan line image processing units using a sentinel, wherein the sentinel is independent of data packets describing the plurality of convex polygons, wherein the sentinel includes a unique pattern configured to signal end of a scan line, wherein the sentinel enters the plurality of scan line imaging processing units separately from the data packets describing the plurality of convex polygons, and the sentinel is controlled to circulate through the plurality of scan line image processing units; and storing image data generated from the scan line image processing units using a plurality of buffers.
