Zusammenfassung:	A method and apparatus for implementing a dynamic display memory is provided. A memory control hub suitable for interposition between a central processor and a memory includes a graphics memory control component. The graphics memory control component determines whether operands accessed by the central processor are graphics operands. If so, the graphics memory control component transforms the virtual address supplied by the central processor to a system address suitable for use in locating the graphics operand in the memory. In one embodiment, the graphics control component maintains a graphics translation table in the memory and utilizes the graphics translation table in transforming virtual addresses to system addresses. Furthermore, in one embodiment, the graphics control component reorders the addresses of the graphics operands to optimize for performance memory accesses by a graphics device.
