摘要： Techniques are disclosed relating to a hardware-supported flexible data structure for graphics processing. In some embodiments, dimensions of the data structure are configurable in an X direction, a Y direction, a number of samples per pixel, and an amount of data per sample. In some embodiments, these attributes are configurable using hardware registers. In some embodiments, the data structure is persistent across a tile being processed such that local memory context is accessible to both rendering threads of a render pass and mid-render compute threads.

摘要： Techniques are disclosed relating to performing mid-render auxiliary compute tasks for graphics processing. In some embodiments, auxiliary compute tasks are performed during a render pass, using at least a portion of a memory context of the render pass, without accessing a shared memory during the render pass. Relative to flushing render data to shared memory to perform compute tasks, this may reduce memory accesses and/or cache thrashing, which may in turn increase performance and/or reduce power consumption.

摘要： Ubershaders may be used in a graphics development environment as an efficiency tool because many options and properties may be captured in a single shader program. Each selectable option of property in the shader code may be tagged with an attribute to indicate the presence of the selection. The single shader program embodying the many selectable options and properties may be compiled to an intermediate version that also embodies the many options and properties, along with at least remnants of the tagging attributes. Upon a request for executable code including indications of the desired selectable options or properties, generation of the executable code may proceed such that it includes only the desire selectable options and properties and not other selectable options and properties embodied in the source code.
摘要翻译： Ubershaders可以在图形开发环境中用作效率工具，因为许多选项和属性可能在单个着色器程序中被捕获。着色器代码中每个可选择的属性选项可以用一个属性进行标记，以指示选择的存在。体现许多可选选项和属性的单个着色器程序可以被编译为也体现了许多选项和属性的中间版本，以及至少残留的标记属性。在请求可执行代码（包括所期望的可选择选项或属性的指示）时，执行可执行代码的生成可以进行，使得其仅包括期望可选择的选项和属性，而不包括源代码中体现的其他可选择的选项和属性。

摘要： Techniques are disclosed relating to memory consistency in a memory hierarchy with relaxed ordering. In some embodiments, an apparatus includes a first level cache that is shared by a plurality of shader processing elements and a second level cache that is shared by the shader processing elements and at least a texture processing unit. In some embodiments, the apparatus is configured to execute operations specified by graphics instructions that include (1) an attribute of the operation that specifies a type of memory consistency to be imposed for the operation and (2) scope information for the attribute that specifies whether the memory consistency specified by the attribute should be enforced at the first level cache or the second level cache. In some embodiments, the apparatus is configured to determine whether to sequence memory accesses at the first level cache and the second level cache based on the attribute and the scope.

摘要： An improved tessellation graphics pipeline that obviates that use of early stage vertex shaders and hull shaders and allows greater efficiency and flexibility. Embodiments provide a graphics pipeline beginning with a tessellator that may obtain tessellation factors in any manner such as reading from a memory of factors provided by a developer or computing the factors using a compute kernel. In some embodiments, a single vertex shader may follow the tessellator and perform all the necessary vertex shading for the pipeline. Furthermore, in some embodiments, a compute kernel is used to generate the tessellation factors. The compute kernel provides flexibility that allows its employment for some graphic portions and not others. In addition, the streamlined pipeline facilitates the efficient use of scaling to determine tessellation factors for the same graphic portion at different camera distances or desired levels of replication of the mathematical model.

摘要： A compiler and library provide the ability to compile a programming language according to a defined language model into a programming language independent, machine independent intermediate representation, for conversion into an executable on a target programmable device. The language model allows writing programs that perform data-parallel graphics and non-graphics tasks.
