    • An apparatus and method utilizes system memory as backing stores so that local graphics memory may be oversubscribed. Surfaces may be paged in and out of system memory based on the amount of usage of the surfaces. The apparatus and method also prioritizes surfaces among different tiers of local memory (e.g. frame buffer), non-local memory (e.g. page locked system memory), and system memory backing stores (e.g. pageable system memory) locations based on predefined criteria and runtime statistics relating to the surfaces. As such, local memory may be, for example, expanded without extra memory costs such as adding a frame buffer memory to allow graphics applications to effectively use more memory and run faster.
    • 一种装置和方法利用系统存储器作为备份存储器,使得局部图形存储器可能被超额认购。 可以基于表面的使用量将表面分页进出系统存储器。 该装置和方法还基于预定义的标准和运行时统计信息优先考虑本地存储器(例如,帧缓冲器),非本地存储器(例如页锁系统存储器)和系统存储器备份存储器(例如可分页系统存储器)位置的不同层之间的表面 涉及表面。 因此,本地存储器可以例如扩展而没有额外的存储器成本,例如添加帧缓冲存储器以允许图形应用程序有效地使用更多的存储器并且运行得更快。
