    Abstract: In one embodiment, a system controls a duty cycle of a processor (e.g. a graphics processing unit (GPU)) to manage power. The GPU may include a snoop indicator that may control whether or not the GPU captures and/or responds to communications from another processor (e.g. a central processing unit (CPU) that executes a driver associate with the GPU). A snooze indicator may control whether or not the GPU is automatically repowered at the start of the next frame, or is repowered only if the communication indicating additional work has been received. In an embodiment, the GPU mode controls discussed above may permit the GPU firmware executed with the GPU itself to control duty cycle power down, independent of the driver executing on the CPU.

    Abstract translation: 在一个实施例中，系统控制处理器（例如，图形处理单元（GPU））的占空比以管理功率。 GPU可以包括窥探指示器，其可以控制GPU是否捕获和/或响应来自另一个处理器（例如，执行与GPU相关联的驱动程序的驱动程序的中央处理单元（CPU））的通信。 打盹指示器可以控制GPU是否在下一帧的开始时自动地被重新供电，或者仅当已经接收到指示附加的工作的通信时被重新供电。 在一个实施例中，上面讨论的GPU模式控制可以允许GPU本身执行的GPU固件控制占空比功率下降，而与在CPU上执行的驱动程序无关。

    Abstract: In an embodiment, a processor that includes multiple cores may implement a power/performance-efficient stop mechanism for power gating. One or more first cores of the multiple cores may have a higher latency stop than one or more second cores of the multiple cores. The power control mechanism may permit continued dispatching of work to the second cores until the first cores have stopped. The power control mechanism may prevent dispatch of additional work once the first cores have stopped, and may power gate the processing in response to the stopping of the second cores. Stopping a core may include one or more of: requesting a context switch from the core or preventing additional work from being dispatched to the core and permitting current work to complete normally. In an embodiment, the processor may be a graphics processing unit (GPU).

    Abstract translation: 在一个实施例中，包括多个核的处理器可以实现用于电力门控的功率/性能效率的停止机制。 多个核心的一个或多个第一核心可以具有比多个核心的一个或多个第二核心更高的延迟停止。 功率控制机构可以允许将工作继续分配到第二个核心，直到第一个核心已经停止。 功率控制机构可以防止在第一个核心停止时发出额外的工作，并且可以响应于第二个核心的停止来对该处理进行加电。 停止核心可能包括以下一个或多个：请求从核心进行上下文切换，或阻止将其他工作分配到核心，并允许当前工作正常完成。 在一个实施例中，处理器可以是图形处理单元（GPU）。

    Abstract: Techniques for anti-aliasing of graphical objects. A graphical object to be displayed on a display image may be modified to include a border region at least partially surrounding the object. The color of the border region may be selected based on the color of the background over which the graphical object is to be displayed. The graphical object is linearly filtered. The linearly filtered graphical object is displayed on a display device.
