摘要： One embodiment of the present invention sets forth a technique for redistributing geometric primitives generated by tessellation and geometry shaders for processing by multiple graphics pipelines. Geometric primitives that are generated in a first processing cycle are collected and redistributed more evenly and in smaller tasks to the multiple graphics pipelines for vertex processing in a second processing cycle. The smaller tasks do not exceed the resource limits of a graphics pipeline and the per-vertex processing workloads of the graphics pipelines in the second cycle are balanced and make full use of resources. Therefore, the performance of the tessellation and geometry shaders is improved.

摘要： A method of organizing memory for storage of texture data, in accordance with one embodiment of the invention, includes accessing a size of a mipmap level of a texture map. A block dimension may be determined based on the size of the mipmap level. A memory space (e.g., computer-readable medium) may be logically divided into a plurality of whole number of blocks of variable dimension. The dimension of the blocks is measured in units of gobs and each gob is of a fixed dimension of bytes. A mipmap level of a texture map may be stored in the memory space. A texel coordinate of said mipmap level may be converted into a byte address of the memory space by determining a gob address of a gob in which the texel coordinate resides and determining a byte address within the particular gob.

摘要： One embodiment of the present invention sets forth a technique for rendering graphics primitives in parallel while maintaining the API primitive ordering. Multiple, independent geometry units perform geometry processing concurrently on different graphics primitives. A primitive distribution scheme delivers primitives concurrently to multiple rasterizers at rates of multiple primitives per clock while maintaining the primitive ordering for each pixel. The multiple, independent rasterizer units perform rasterization concurrently on one or more graphics primitives, enabling the rendering of multiple primitives per system clock.

摘要： Circuits, methods, and apparatus that provide texture caches and related circuits that store and retrieve texels in a fast and efficient manner. One such texture circuit provides an increased number of bilerps for each pixel in a group of pixels, particularly when trilinear or aniso filtering is needed. For trilinear filtering, texels in a first and second level of detail are retrieved for a number of pixels during a clock cycle. When aniso filtering is performed, multiple bilerps can be retrieved for each of a number of pixels during one clock cycle.

摘要： A system and method are provided for accelerating graphics processing utilizing multiple-pass rendering. Initially, geometry operations are performed on graphics data, and the graphics data is stored in memory. During a first rendering pass, various operations take place. For example, the graphics data is read from the memory, and the graphics data is rasterized. Moreover, first z-culling operations are performed utilizing the graphics data. Such first z-culling operations maintain a first occlusion image. During a second rendering pass, the graphics data is read from memory. Still yet, the graphics data is rasterized and second z-culling operations are performed utilizing the graphics data and the first occlusion image. Moreover, visibility operations are performed utilizing the graphics data and a second occlusion image. Raster-processor operations are also performed utilizing the graphics data, during the second rendering pass.

摘要： A system and method for tracking and reporting texture map levels of detail that are computed during graphics processing allows for efficient management of texture map storage. Minimum and/or maximum pre-clamped texture map levels of detail values are tracked by a graphics processor and an array stored in memory is updated to report the minimum and/or maximum values for use by an application program. The minimum and/or maximum values may be used to determine the active set of texture map levels of detail that is loaded into graphics memory.
