摘要： An integrated graphics pipeline system is provided for graphics processing. Such system includes a tessellation module that is positioned on a single semiconductor platform for receiving data for tessellation purposes. Tessellation refers to the process of decomposing either a complex surface such as a sphere or surface patch into simpler primitives such as triangles or quadrilaterals, or a triangle into multiple smaller triangles. Also included on the single semiconductor platform is a transform module adapted to transform the tessellated data from a first space to a second space. Coupled to the transform module is a lighting module which is positioned on the single semiconductor platform for performing lighting operations on the data received from the transform module. Also included is a rasterizer coupled to the lighting module and positioned on the single semiconductor platform for rendering the data received from the lighting module.

摘要： The present invention provides alignment and ordering of vector elements for SIMD processing. In the alignment of vector elements for SIMD processing, one vector is loaded from a memory unit into a first register and another vector is loaded from the memory unit into a second register. The first vector contains a first byte of an aligned vector to be generated. Then, a starting byte specifying the first byte of an aligned vector is determined. Next, a vector is extracted from the first register and the second register beginning from the first bit in the first byte of the first register continuing through the bits in the second register. Finally, the extracted vector is replicated into a third register such that the third register contains a plurality of elements aligned for SIMD processing. In the ordering of vector elements for SIMD processing, a first vector is loaded from a memory unit into a first register and a second vector is loaded from the memory unit into a second register. Then, a subset of elements are selected from the first register and the second register. The elements from the subset are then replicated into the elements in the third register in a particular order suitable for subsequent SIMD vector processing.

摘要： Systems and methods for addressing memory using non-power-of-two virtual memory page sizes improve graphics memory bandwidth by distributing graphics data for efficient access during rendering. Various partition strides may be selected for each virtual memory page to modify the number of sequential addresses mapped to each physical memory partition and change the interleaving granularity. The addressing scheme allows for modification of a bank interleave pattern for each virtual memory page to reduce bank conflicts and improve memory bandwidth utilization. The addressing scheme also allows for modification of a partition interleave pattern for each virtual memory page to distribute accesses amongst multiple partitions and improve memory bandwidth utilization.

摘要： A virtual architecture and instruction set support explicit parallel-thread computing. The virtual architecture defines a virtual processor that supports concurrent execution of multiple virtual threads with multiple levels of data sharing and coordination (e.g., synchronization) between different virtual threads, as well as a virtual execution driver that controls the virtual processor. A virtual instruction set architecture for the virtual processor is used to define behavior of a virtual thread and includes instructions related to parallel thread behavior, e.g., data sharing and synchronization. Using the virtual platform, programmers can develop application programs in which virtual threads execute concurrently to process data; virtual translators and drivers adapt the application code to particular hardware on which it is to execute, transparently to the programmer.

摘要： Method and apparatus for neighbor and edge indexing is described. A vertex is identified and assigned a reference. One-ring neighbor vertices of the vertex are identified. The reference is assigned to each of the one-ring neighbor vertices identified. An index to one of the one-ring neighbor vertices is assigned. The index is successively incremented to provide indices for each of the one-ring neighbor vertices remaining. Edge indexing follows as described above, with the vertex and its one-ring neighbors defining end points of edges. Additionally, offset indexing is described, and may be used for a consistent order of computation.

摘要： Method and apparatus for generating a primitive extension defining a generalized primitive is described. The primitive extension defines the connectivity and vertices used to specify a collection of connected primitives, such as a strip-type or fan-type generalized primitive. A generalized primitive includes a number of vertices where some of the vertices are shared with neighboring primitives. The primitive extension includes an originating primitive, vertex data, and connectivity information. The primitive extension provides a general interface for describing a variety of connected primitives.
