摘要： An apparatus and method are described for culling commands in a tile-based renderer. For example, one embodiment of an apparatus comprises: a command buffer to store a plurality of commands to be executed by a render pipeline to render a plurality of tiles; visibility analysis circuitry to determine per-tile visibility information for each of the plurality of tiles and to store the visibility information for a first tile in a first storage, the visibility information specifying either that all of the commands associated with rendering the first tile can be skipped or identifying individual commands associated with rendering the first tile that can be skipped; and a render pipeline to read the visibility information from the first storage to determine whether to execute or skip one or more of the commands from the command buffer to render the first tile.

摘要： For a given texture address, a multi-mode texture sampler fetches and reduces texture data with a multi-mode filter accumulator suitable for providing a weighted average over a variety of filter footprints. A multi-mode texture sampler is configurable to provide both a wide variety of footprints and allow for a filter footprint significantly wider than the bi-linear (2×2 texel) footprint. In embodiments, filter coefficients specifying a weighting for each texel in a flexible footprint are cached from coefficient tables stored in memory. Techniques and systems are provided for dynamic allocation, update and handling of weighting coefficient tables as resources independent of sampler state.

摘要： Various embodiments are presented herein that may reduce the workload of a GPU tasked with delivering frames of video data to a display generated by a 3D application executing within a system or computing platform. 3D applications executing within the system may generate new frames of video content at a specified frame rate known as frames per second (FPS). These frames are then delivered to a display communicatively coupled with the system for rendering. Every display has a refresh rate specified in cycles per second or Hertz (Hz). Vertical Synchronization (VSYNC) is a setting that synchronizes the frames per second (FPS) of a given application with the display's refresh rate. Forcing VSYNC on the application while the system is operating on battery power may reduce the workload on the GPU when the FPS is greater than the refresh rate resulting in greater battery life.

摘要翻译：本文给出了各种实施例，其可以减少将视频数据帧传送到在系统或计算平台内执行的3D应用所生成的显示器的GPU所负责的工作量。在系统内执行的3D应用可以以指定的帧速率（FPS）产生新的视频内容帧。然后将这些帧传送到与系统通信地耦合以进行渲染的显示器。每个显示器的刷新率都以每秒周期或赫兹（Hz）指定。垂直同步（VSYNC）是一种使显示器刷新率同步给定应用程序的每秒帧数（FPS）的设置。当系统使用电池供电时，在应用程序上强制VSYNC可能会在FPS大于刷新率导致更长的电池寿命时减少GPU上的工作量。

摘要： Various embodiments enable loop processing in a command processing block of the graphics hardware. Such hardware may include a processor including a command buffer, and a graphics command parser. The graphics command parser to load graphics commands from the command buffer, parse a first graphics command, store a loop count value associated with the first graphics command, parse a second graphics command and store a loop wrap address based on the second graphics command. The graphics command parser may execute a command sequence identified by the second graphics command, parse a third graphics command, the third graphics command identifying an end of the command sequence, set a new loop count value, and iteratively execute the command sequence using the loop wrap address based on the new loop count value.
