摘要： A central processing unit (CPU) including an operating system for executing code segments capable of performing graphics processing on the CPU. Associated therewith is a graphics application specific integrated circuit (ASIC) for performing graphics processing in accordance with a graphics processing standard. An extension to the software is included that identifies a first portion of the graphics processing to be performed on the graphics ASIC and a second portion of the graphics processing to be performed on the CPU. Such second portion of the graphics processing includes application-programmable vertex processing unavailable by the graphics ASIC. A compiler compiles the software to execute the first portion of the graphics processing on the graphics ASIC and the second portion of the graphics processing on the CPU in accordance with the extension.

摘要： Systems and methods for compiling programs using condition codes and executing those programs when non-numeric values are present allow for explicit handling of non-numeric values. In addition to the conventional condition code values of positive, negative, and zero, a fourth value may be encoded, not a number (NaN) representing a non-numeric value. New condition tests are defined that explicitly account for condition code values of NaN. A compiler may produce code using the new condition tests to represent if and if-else statements. The code including the new condition tests generates deterministic results during execution when non-numeric values are present.

摘要： One embodiment of the present invention sets forth a technique for a program to access multi-dimensional formatted graphics surface memory. Multi-dimensional memory objects called “surfaces” stored in a user-specified data or pixel format and arranged in a graphics optimized layout are accessed by programs using surface instructions. A set of memory access instructions e.g., load, store, reduce, and atomic, referred to as surface instructions, may be used to access the surfaces. Coordinate bounds checking is performed with configurable clamping. Caching behavior may also be specified by the surface instructions. Data format conversion and packing to a specified storage format is supported for store, reduction, and atomic surface instructions. Data format conversion and unpacking from a specified storage format is supported for loads and atomic surface instructions.

摘要： One embodiment of the present invention sets forth a technique controlling the pixel location at which the plane equation is evaluated. Multiple pixel offsets (dx, dy) may be specified that each define to a sub-pixel sample position. Attributes are then calculated for each sub-pixel sample position that is covered by a geometric primitive. One advantage of the technique is that anti-aliasing quality may be improved since high frequency color components may be selectively supersampled for particular geometric primitives.

摘要： One embodiment of the present invention sets forth a technique for generating a batch clip state stored in clip state machine (CSM) associated with a batch of vertices. Per-vertex clip state is generated for each vertex in the batch of vertices based on the position of each vertex relative to each clip plane. For a given vertex, per-vertex clip state indicates whether the vertex is inside or outside each of the one or more clip planes. The per-vertex clip states of all the vertices in the batch of vertices are coalesced into a batch clip state by determining whether each vertex in the batch of vertices is inside every clip plane, each vertex is outside at least one clip plane or neither. The batch clip state is stored in the CSM associated with the thread group that processes the batch of vertices that can be accessed by further stages of the graphics pipeline.
摘要翻译： 本发明的一个实施例提出了一种用于生成与一批顶点相关联的剪辑状态机（CSM）中存储的批次剪辑状态的技术。 基于每个顶点相对于每个剪切平面的位置，为顶点批次中的每个顶点生成每顶点剪辑状态。 对于给定的顶点，每顶点剪辑状态指示顶点是在每个一个或多个剪辑平面的内部还是外部。 通过确定顶点批次中的每个顶点是否位于每个剪切平面内，每个顶点至少在一个剪切平面之外，或者两个顶点都在外部至少一个剪切平面，否则将批次顶点中的所有顶点的每顶点剪辑状态合并为批次剪辑状态。 批处理剪辑状态存储在与线程组相关联的CSM中，处理可以通过图形流水线的更多阶段访问的顶点批次。
