ABSTRACT:
A processing unit (11) for a printer system. The processing unit (11) is comprised of a master processor (21) and multiple parallel processors (22). The master processor (21) builds a display list and partitions it into sublists, which it distributes to the parallel processors (22). The parallel processors (22) interpret the sublists, thereby rendering the image as bitmapped data. Interpretation of a sublist is performed by reading its operation codes and calling rasterizing primitives represented by the operation codes. (FIG. 3). During execution of a rasterizing primitive, a parallel processor (22) determines whether the next operation code in the sublist will call the same primitive. If so, execution of the current primitive is repeated.
