摘要： One embodiment of the present invention sets forth a technique for reducing overhead associated with transmitting primitive draw commands from memory to a graphics processing unit (GPU). Command pairs comprising an end draw command and a begin draw command associated with a conventional graphics application programming interface (API) are selectively replaced with a new construct. The new construct is a reset topology index, which implements a combined function of the end draw command and begin draw command. The new construct improves efficiency by reducing total data transmitted from memory to the GPU.

摘要： One embodiment of the present invention sets forth a technique for splitting a set of vertices into a plurality of batches for processing. The method includes receiving one or more primitives each containing an associated set of vertices. For each of the one or more primitives, one or more vertices are gathered from the set of vertices, the vertices are arranged into one or more batches, the batch is routed to a processing pipeline line to process each batch as a separate primitive, and the one or more batches are processed to produce results identical to those of processing the entire primitive as a single entity.

摘要： One embodiment of the present invention sets forth a technique for reducing the overhead for transmitting explicit begin and explicit end commands that are needed in primitive draw command sequences. A draw method includes a header to specify an implicit begin command, an implicit end command, and instancing information for a primitive draw command sequence. The header is followed by a packet including one or more data words (dwords) that each specify a primitive topology, starting offset into a vertex or index buffer, and vertex or index count. Only a single clock cycle is consumed to transmit and process the header. The performance of graphics application programs that have many small batches of geometry (as is typical of many workstation applications) may be improved since the overhead of transmitting and processing the explicit begin and explicit end draw commands is reduced.

摘要： One embodiment of the present invention sets forth a technique for selecting a first processor included in a plurality of processors to receive work related to a compute task. The technique involves analyzing state data of each processor in the plurality of processors to identify one or more processors that have already been assigned one compute task and are eligible to receive work related to the one compute task, receiving, from each of the one or more processors identified as eligible, an availability value that indicates the capacity of the processor to receive new work, selecting a first processor to receive work related to the one compute task based on the availability values received from the one or more processors, and issuing, to the first processor via a cooperative thread array (CTA), the work related to the one compute task.

摘要： One embodiment of the present invention sets forth a technique for reducing the amount of memory required to store vertex data processed within a processing pipeline that includes a plurality of shading engines. The method includes determining a first active shading engine and a second active shading engine included within the processing pipeline, wherein the second active shading engine receives vertex data output by the first active shading engine. An output map is received and indicates one or more attributes that are included in the vertex data and output by the first active shading engine. An input map is received and indicates one or more attributes that are included in the vertex data and received by the second active shading engine from the first active shading engine. Then, a buffer map is generated based on the input map, the output map, and a pre-defined set of rules that includes rule data associated with both the first shading engine and the second shading engine, wherein the buffer map indicates one or more attributes that are included in the vertex data and stored in a memory that is accessible by both the first active shading engine and the second active shading engine.

摘要： Method and apparatus for display image adjustment is described. More particularly, handles associated with polygon vertices of a polygon rendered image are provided as a graphical user interface (GUI). These handles may be selected and moved by a user with a cursor pointing device to adjust a displayed image for keystoning, among other types of distortion. This GUI allows a user to adjust a projected image for position of a projector with respect to imaging surface, as well as for imaging surface contour, where such contour may be at least substantially planar, cylindrical, or spherical and where such contour may comprise multiple imaging surfaces. This advantageously may be done without special optics or special equipment. An original image is used as texture for rendering polygons, where the image is applied to the rendered polygons.

摘要： A deferred graphics pipeline processor comprising a texture unit and a texture memory associated with the texture unit. The texture unit applies texture maps stored in the texture memory, to pixel fragments. The textures are MIP-mapped and comprise a series of texture maps at different levels of detail, each map representing the appearance of the texture at a given distance from an eye point. The texture unit performs tri-linear interpolation from the texture maps to produce a texture value for a given pixel fragment that approximates the correct level of detail. The texture memory has texture data stored and accessed in a manner which reduces memory access conflicts and thus improves throughput of said texture unit.
