Abstract
A method, computer program product, and system are provided for processing a graphics operation. For instance, the method can include partitioning a texture and associated mipmaps into memory tiles, where the memory tiles are associated with a virtual memory system. The method can also include mapping a first subset of the memory tiles to respective address spaces in a physical memory system. Further, the method can include accessing the physical memory system during a rendering process of a graphics scene associated with the first subset of memory tiles. In the instance when the graphics scene requires one or more memory tiles outside of the first subset of memory tiles, the method can also include mapping a second subset of memory tiles to respective address spaces in the physical memory system.
