摘要： Systems and methods for providing on-demand memory management. In response to a mapping request from a device driver or other program, a first portion of the memory is mapped to one or more virtual addresses in a first region of a virtual memory space so that it can be directly accessed by the CPU. In response to an unmapping request the first portion of the memory is unmapped. Mapping and unmapping requests may be made at any time.
摘要翻译： 用于提供按需内存管理的系统和方法。 响应于来自设备驱动器或其他程序的映射请求，存储器的第一部分被映射到虚拟存储器空间的第一区域中的一个或多个虚拟地址，使得其可以被CPU直接访问。 响应于非映射请求，存储器的第一部分被取消映射。 可以随时进行映射和取消映射请求。

摘要： A low cost high performance three dimensional (3D) graphics system is disclosed that can model a world in three dimensions and project the model onto a two dimensional viewing plane selected based on a changeable viewpoint. The viewpoint can be changed on an interactive, real time basis by operating user input controls such as game controllers. The system rapidly produces a corresponding changing image (which can include animated cartoon characters or other animation) on the screen of a color television set. The richly featured high performance low cost system is intended to give consumers the change to interact in real time right inside magnificent virtual 3D worlds to provide a high degree of image realism, excitement and flexibility. An optimum feature set/architecture (including a custom designed graphics/audio coprocessor) provides high quality fast moving 3D images and digital stereo sound for video game play and other graphics applications. Numerous features provide flexibility and capabilities in a system that is intended to be within the cost range of most consumers.
