In a virtual memory system, address translation information is provided using a cluster that is associated with some range of virtual addresses and that can be used to translate any virtual address in its range to a physical address, where the sizes of the ranges mapped by different clusters may be different. Clusters are stored in an address translation table that is indexed by virtual address so that, starting from any valid virtual address, the appropriate cluster for translating that address can be retrieved from the translation table. The clusters are dynamically created from a fragmented pool of physical addresses as new virtual address mappings are requested by consumers of the virtual memory space.

Memory management for virtual address space with translation units of variable range size

A method, system, and computer program product sends scene data to a geometry engine, wherein a processor generates scene data for a frame in accordance with an application program, and writes the scene data to a first memory location, known hereinafter as an intermediate buffer. Scene data for the next frame is then generated and written to a second intermediate buffer, while a geometry engine reads and renders the scene data in the first intermediate buffer. Scene data for the following frame is then generated and written to the first intermediate buffer, while a geometry engine reads and renders the scene data in the second intermediate buffer. The process continues in this manner until the application program is finished executing.
