Abstract: A method and apparatus for configuring multiple displays includes determining, in connection with an image or portion thereof to be displayed on the multiple displays at the same time, whether received display preferences can be fulfilled in observance of: configuration properties of the multiple displays and configuration properties of a computing system, such as the capabilities of display controllers. The method and apparatus also determine whether a current configuration of the multiple displays to the computing system can be reconfigured such that the display preferences of the multiple displays can be fulfilled at the same time while maintaining effective configuration of a current configuration when the display preferences cannot be fulfilled, and display the images of a portion thereof on the multiple displays at the same time.

Abstract: A method and apparatus for configuring multiple displays associated with a computing system begins when display preferences regarding at least one of the multiple displays are received. The display preferences indicate desired selections of which images are to be displayed on which displays and may be based on user selections or application selections. Having received the display preferences, a coupling controller within a video graphics processing circuit determines whether the display preferences can be fulfilled in observance of configuration properties. The configuration properties include limitations of the displays (e.g., refresh rate, resolution) and the computing system (e.g., display controller capabilities) and/or rules of the computing system (e.g., at least one screen must be actively coupled at all times). If the display preferences can be fulfilled, the coupling controller causes display controllers to be operably coupled to displays.

Abstract: A method and apparatus for memory allocation in a multi-processor system is accomplished by mapping portions of a shared memory to a first and second processor. The mapping is performed such that either of the processors' portions can be enlarged or reduced based on the memory that is located between the portions allocated to the processors. When a processor requests additional memory and there is sufficient free memory between the processors' respective portions, the appropriate amount of the free memory is allocated to the requesting processor.
