  • Patent number: 6326975
    Abstract: A process and implementing computer system for graphics applications in which information files such as texture maps (TMs) are prioritized and stored in a local relatively fast RDRAM memory. The method of prioritization includes initially sorting the information files by order of the frequency with which corresponding graphics primitive elements are called by the application. The priority is adjusted such that the smaller TMs get an increase in their priority so that more TMs may be placed in faster graphics memory. Thereafter among similarly prioritized groups of information files, the larger of the files are first stored in the fast graphics memory and the remaining files are marked for storage in the system memory after the fast local memory has been fully utilized.
