Abstract

A method for formatting a texture in a frame buffer is accomplished by receiving a lock signal from a processor, where the lock signal is associated with the texture. A pointer to a location in the frame buffer is provided in response to the lock signal, whereupon the processor stores the texture in the frame buffer at the specified location. An unlock signal is then received from the processor, indicating that the texture has been stored. The texture is then copied from the frame buffer to a memory based on a tiling algorithm to produce a tiled version of the texture in the memory. The tiled version is then copied from the memory back to the frame buffer at the specified location.
