    摘要： A method and apparatus for processing graphics primitives that includes a trivial discard guard band. Such a trivial discard guard band is used for comparison operations with the vertices of graphics primitives to determine whether the graphics primitives can be trivially discarded such that no further processing of the primitives is performed. The trivial discard guard band may be based on the specific dimensions of primitives such as one-half of the width of the line primitives or the radial dimension of point primitives such that the rasterization area of such primitives is taken into account when trivial discard decisions are performed.

    摘要： A rasterizer comprised of a bounding box calculator, a plane converter, a windower, and incrementers. For each polygon to be processed, a bounding box calculation is performed which determines the display screen area, in spans, that totally encloses the polygon and passes the data to the plane converter. The plane converter also receives as input attribute values for each vertex of the polygon. The plane converter computes planar coefficients for each attribute of the polygon, for each of the edges of the polygon. The plane converter unit computes the start pixel center location at a start span and a starting coefficient value at that pixel center. The computed coefficients also include the rate of change or gradient, for each polygon attribute in the x and y directions, respectively. The plane converter also computes line coefficients for each of the edges of the polygon. Line equation values are passed through to the windower where further calculations allow the windower to determine which spans are either covered or intersected by the polygon. The incrementers receive the span coverage data from the windower in addition to receiving planar coefficient values from the plane converter. The incrementers utilize the data from both the windower and plane converter to walk or traverse the polygon in those intersected spans, pixel by pixel. As the incrementer visits each pixel, vertex attribute values are interpolated to each pixel.

    摘要： A processor includes a first shader engine and a second shader engine. The first shader engine is configured to process pixel shaders for a first subset of pixels to be displayed on a display device. The second shader engine is configured to process pixel shaders for a second subset of pixels to be displayed on the display device. Both the first and second shader engines are also configured to process general-compute shaders and non-pixel graphics shaders. The processor may also include a level-one (L1) data cache, coupled to and positioned between the first and second shader engines.

    摘要： A method of allocating a memory to a plurality of concurrent threads is presented. The method includes dynamically determining writer threads each having at least one pending write to the memory; and dynamically allocating respective contiguous blocks in the memory for each of the writer threads. Another method of allocating a memory to a plurality of concurrent threads includes launching the plurality of threads as a plurality of wavefronts, dynamically determining a group of wavefronts each having at least one thread requiring a write to the memory, and dynamically allocating respective contiguous blocks in the memory for each wavefront from the group of wavefronts. A corresponding method of assigning a memory to a plurality of reader threads includes determining a first number corresponding to a number of writer threads having a block allocated in said memory, launching a first number of reader threads, entering a first wavefront of said reader threads from said group of wavefronts to an atomic operation, and assigning a first block in the memory to the first wavefront during the corresponding atomic operation, where the first block is contiguous to a previously allocated block dynamically allocated to another wavefront from said group of wavefronts. Corresponding system embodiments and computer program product embodiments are also presented.

    摘要： A system, method, and computer program product are provided for improving resource utilization of multithreaded applications. Rather than requiring threads to block while waiting for data from a channel or requiring context switching to minimize blocking, the techniques disclosed herein provide an event-driven approach to launch kernels only when needed to perform operations on channel data, and then terminate in order to free resources. These operations are handled efficiently in hardware, but are flexible enough to be implemented in all manner of programming models.

    摘要： An apparatus with circuit redundancy includes a set of parallel arithmetic logic units (ALUs), a redundant parallel ALU, input data shifting logic that is coupled to the set of parallel ALUs and that is operatively coupled to the redundant parallel ALU. The input data shifting logic shifts input data for a defective ALU, in a first direction, to a neighboring ALU in the set. When the neighboring ALU is the last or end ALU in the set, the shifting logic continues to shift the input data for the end ALU that is not defective, to the redundant parallel ALU. The redundant parallel ALU then operates for the defective ALU. Output data shifting logic is coupled to an output of the parallel redundant ALU and all other ALU outputs to shift the output data in a second and opposite direction than the input shifting logic, to realign output of data for continued processing, including for storage or for further processing by other circuitry.

    摘要： Briefly, graphics data processing logic includes a plurality of parallel arithmetic logic units (ALUs), such as floating point processors or any other suitable logic, that operate as a vector processor on at least one of pixel data and vertex data (or both) and a programmable storage element that contains data representing which of the plurality of arithmetic logic units are not to receive data for processing. The graphics data processing logic also includes parallel ALU data packing logic that is operatively coupled to the plurality of arithmetic logic processing units and to the programmable storage element to pack data only for the plurality of arithmetic logic units identified by the data in the programmable storage element as being enabled.
