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.

Using a processor enhanced memory module to accelerate hardcopy image processing within existing printer controller

A set of related methods for detecting the existence and exact nature of any rearrangements and/or inversions of address lines and/or data lines to a memory device, relative to a second set of address lines and/or data lines to the same memory, are disclosed. Moreover, a set of related methods for correcting these relative rearrangements and/or inversions are disclosed. These methods allow meaningful access to memory shared by two or more devices using different address and data paths in the case where the relative nature of the address and data paths is unknown a priori. These methods of detecting and correcting such mismatches in separate address and data lines to shared memory may be implemented either in hardware or software or a combination of both.

A computer system includes a main processing unit ( ) coupled to a DSP/memory module ( ). The DSP/memory module ( ) includes semiconductor memory ( ) and digital signal processor circuitry ( ) including one or more digital signal processors ( ). The DSP/memory module ( ) may be placed in standard main memory sockets, such as a SIMM or DIMM sockets, and used as conventional main memory. The memory module can also be used in a smart mode, wherein the digital signal processor ( ) performs operations on data for retrieval by the main processing unit ( ).

In a virtual reality system (20) an operator perceives being in a virtual reality world (74) of virtual reality images (62). The system (20) models the relative position and movement of objects (208 and 210) in a virtual reality world (74) by representing graphically a first (208) and second (210) object in a virtual reality world (74) on a graphical display (60 and 68). The representation selective obscures the first (208) and second (210) objects according to the relative position of the objects (208 and 210) to a predetermined observation point in the virtual reality world (74). The system (20) then determines a first partitioning plane (204) between the first (208) and second (210) objects. Then, the system (20) method determines a second partition plane (206) between the first (208) and second (210) object in response to either of said first (208) or second (210) objects moving across the first partitioning plane (204). Then, the system (20) graphically represent on the graphical display (60 and 68) the first (208) and second (210) objects within the virtual reality world (74) by selectively obscuring the first (208) and second (210) objects according to their relative position to the predetermined observation point.
