摘要： Video frame buffers are controlled using a sequence of new-frame-indicators (e.g., FLIP) and no-new-frame-indicators (e.g., NOFLIP) in a frame indicator queue that is accessed with each display refresh. Video samples are loaded into a chain of video frame buffers that is “rotated” during the vertical blanking signal of the display to swap an old frame buffer out for a new frame buffer. The rotations of the frame buffer chain are controlled based on the frame indicators in the frame indicator queue to present new video samples to the display in a regular pattern, thereby providing smooth video playback.
摘要翻译：在每个显示刷新访问的帧指示符队列中，使用新帧指示符序列（例如，FLIP）和无新帧指示符（例如，NOFLIP）来控制视频帧缓冲器。视频样本被加载到视频帧缓冲器链中，该视频帧缓冲器在显示器的垂直消隐信号期间被“旋转”，以将新的帧缓冲器交换出来用于新的帧缓冲器。基于帧指示符队列中的帧指示符来控制帧缓冲链的转动，以规则模式将新的视频样本呈现给显示器，从而提供平滑的视频回放。

摘要： Atlasing and virtual surface techniques are described. In one or more implementations, virtual surface functionality is exposed by an operating system for access by one or more applications of the computing device. A virtual surface is created in response to a request from the one or more applications to be used to render visuals for display by a display device. The virtual surface is allocated in memory of the computing device by the exposed virtual surface functionality to have an area that is larger than an area to be used to display the visuals from the one or more applications.

摘要： Complex computer graphics forms and motions can be constructed either by hand or with motion or geometry capture technologies, once they are created, they are difficult to modify, particularly at runtime. Interpolation provides a way to leverage artist-generated source material. Methodologies for efficient runtime interpolation between multiple forms or multiple motion segments enables computers to perform more realistic animation in real-time. Shape interpolation is applied to predefined figures to create smoothly skinned figures that deform in natural ways. Predefined figures are selected using a search technique that reduces the amount of interpolation required to produce real-time animation.

摘要： Systems and methods that independently control divided and/or isolated processing resources of a Graphical Processing Unit (GPU). Synchronization primitives for processing are shared among such resources to process interaction with the engines and their associated different requirements (e.g. different language). Accordingly, independent threads can be created against particular nodes (e.g., a video engine node, 3D engine node), wherein multiple engines can exist under a single node, and independent control can subsequently be exerted upon the plurality of engines associated with the GPU.

摘要： Systems and methods are provided for scheduling the processing of a coprocessor whereby applications can submit tasks to a scheduler, and the scheduler can determine how much processing each application is entitled to as well as an order for processing. In connection with this process, tasks that require processing can be stored in physical memory or in virtual memory that is managed by a memory manager. The invention also provides various techniques of determining whether a particular task is ready for processing. A “run list” may be employed to ensure that the coprocessor does not waste time between tasks or after an interruption. The invention also provides techniques for ensuring the security of a computer system, by not allowing applications to modify portions of memory that are integral to maintaining the proper functioning of system operations.

摘要： Systems and methods for scheduling coprocessing resources in a computing system are provided without redesigning the coprocessor. In various embodiments, a system of preemptive multitasking is provided achieving benefits over cooperative multitasking by any one or more of (1) executing rendering commands sent to the coprocessor in a different order than they were submitted by applications; (2) preempting the coprocessor during scheduling of non-interruptible hardware; (3) allowing user mode drivers to build work items using command buffers in a way that does not compromise security; (4) preparing DMA buffers for execution while the coprocessor is busy executing a previously prepared DMA buffer; (5) resuming interrupted DMA buffers; and (6) reducing the amount of memory needed to run translated DMA buffers.

摘要： Techniques for minimizing coprocessor “starvation,” and for effectively scheduling processing in a coprocessor for greater efficiency and power. A run list is provided allowing a coprocessor to switch from one task to the next, without waiting for CPU intervention. A method called “surface faulting” allows a coprocessor to fault at the beginning of a large task rather than somewhere in the middle of the task. DMA control instructions, namely a “fence,” a “trap” and a “enable/disable context switching,” can be inserted into a processing stream to cause a coprocessor to perform tasks that enhance coprocessor efficiency and power. These instructions can also be used to build high-level synchronization objects. Finally, a “flip” technique is described that can switch a base reference for a display from one location to another, thereby changing the entire display surface.
