摘要： A scalable shader architecture is disclosed. In accord with that architecture, a shader includes multiple shader pipelines, each of which can perform processing operations on rasterized pixel data. Shader pipelines can be functionally removed as required, thus preventing a defective shader pipeline from causing a chip rejection. The shader includes a shader distributor that processes rasterized pixel data and then selectively distributes the processed rasterized pixel data to the various shader pipelines, beneficially in a manner that balances workloads. A shader collector formats the outputs of the various shader pipelines into proper order to form shaded pixel data. A shader instruction processor (scheduler) programs the individual shader pipelines to perform their intended tasks. Each shader pipeline has a shader gatekeeper that interacts with the shader distributor and with the shader instruction processor such that pixel data that passes through the shader pipelines is controlled and processed as required.

摘要： A pixel center position that is not covered by a primitive covering a portion of the pixel is displaced to lie within a fragment formed by the intersection of the primitive and the pixel. X,y coordinates of a pixel center are adjusted to displace the pixel center position to lie within the fragment, affecting actual texture map coordinates or barycentric weights. Alternatively, a centroid sub-pixel sample position is determined based on coverage data for the pixel and a multisample mode. The centroid sub-pixel sample position is used to compute pixel or sub-pixel parameters for the fragment.

摘要： A fragment processor includes a fragment shader distributor, a fragment shader collector, and a plurality of fragment shader pipelines. Each fragment shader pipeline executes a fragment shader program on a segment of fragments. The plurality of fragment shader pipelines operate in parallel, executing the same or different fragment shader programs. The fragment shader distributor receives a stream of fragments from a rasterization unit and dispatches a portion of the stream of fragments to a selected fragment shader pipeline until the capacity of the selected fragment shader pipeline is reached. The fragment shader distributor then selects another fragment shader pipeline. The capacity of each of the fragment shader pipelines is limited by several different resources. As the fragment shader distributor dispatches fragments, it tracks the remaining available resources of the selected fragment shader pipeline. A fragment shader collector retrieves processed fragments from the plurality of fragment shader pipelines.

摘要： A method and system for patching instructions in a 3-D graphics pipeline. Specifically, in one embodiment, instructions to be executed within a scheduling process for a shader pipeline of the 3-D graphics pipeline are patchable. A scheduler includes a decode table, an expansion table, and a resource table that are each patchable. The decode table translates high level instructions to an appropriate microcode sequence. The patchable expansion table expands a high level instruction to a program of microcode if the high level instruction is complex. The resource table assigns the units for executing the microcode. Addresses within each of the tables can be patched to modify existing instructions and create new instructions. That is, contents in each address in the tables that are tagged can be replaced with a patch value of a corresponding register.

摘要： A surface generated from a radiosity simulation is shaded. The surface is divided into a plurality of elements and a brightness value is calculated for each of the elements. An initial surface shading is defined in which the resolution of shading is determined in response to the highest element density of the surface. Element brightness values are processed to generate brightness values for the initial surface shading and values of the initial surface shading are filtered to generate brightness values for an enhanced surface shading. Brightness values of a plurality of elements may be combined to generate a single texel brightness value in the initial surface shading. The filtering step may include steps of increasing the resolution of the initial surface shading and filtering the increased resolution shading. A galcion filtering process may be performed.
