Abstract
A computer imager for processing computerized data receives signals in PostScript format. An interpreter generates compressed data signals for presentation to a rasterizer. The rasterizer and interpreter utilize parallel processing and differentiate between character, graphic and contone image page elements, each of which is processed in a different manner to maximize speed and minimize memory and other imager component utilization. Decompressed and rasterized data is presented to a graphics accelerator that includes separate circuitry for processing character and graphics/image data. There is also circuitry to resolve page location conflicts. A halftone unit is included and receives the resolved, rasterized data for presentation to a video interface and ultimately a printer or other output imaging device.
