Abstract
The processor enhanced memory module PEMM can be incorporated into the hardcopy image processing pipeline of existing printer controllers by using the smart memory model. Here the data generated from RISC based PDL interpretation or pre-rasterized data can be processed in an accelerated fashion into page bit maps, color space converted, and compressed by the PEMM. Since the DSP on the PEMM is programmable, the resolution, color space, and type of compression along with other printer specific processing can have formats other than those determined by the fixed functionality of the ASIC devices present in the pipeline.
