Abstract

A texture mapping computer graphics system includes a host computer having a system memory that stores texture data. A graphics hardware device, coupled to the host computer, renders texture mapped images, and includes a local memory that stores at least a portion of the texture data stored in the system memory at any one time. A software daemon runs on the processor of the host computer and manages transferring texture data from the system memory to the local memory when needed by the hardware device to render an image. The software daemon monitors use by the hardware device of texture data blocks stored in the local memory. The daemon also tracks the priorities of the texture stored in the main memory so that lowest priority and least recently used texture data blocks in the local memory are replaced with texture data blocks needed by the hardware device to render images.
