摘要： The present invention is a unified shader unit used in texture processing in graphics processing device. Unlike the conventional method of using one shader for texture coordinate shading and another for color shading, the present shader performs both operations. The unified shader uses the same precision for both texture coordinate and color shading, thus simplifying the complexity of programming for two separate conventional shaders with different levels of precision. Furthermore, the present invention uses enhanced scheduling logic to perform indirect texture and bump mapping in a single first-in, first-out (FIFO) memory structure and avoids the problems associated with large FIFOs with buffer registers found in conventional shaders. In one embodiment, a plurality of ALU-memory pairs are synchronized to form a plurality of pipelines to execution shading instructions. In another embodiment, a plurality of unified shaders are synchronized and connected together to processing shading operations concurrently.
摘要翻译：本发明是用于图形处理装置中的纹理处理的统一着色器单元。与使用一个着色器进行纹理坐标着色而另一个用于色彩着色的常规方法不同，本着色器执行两个操作。统一着色器对于纹理坐标和颜色着色使用相同的精度，从而简化了具有不同精度级别的两个独立常规着色器的编程复杂度。此外，本发明使用增强的调度逻辑在单个先入先出（FIFO）存储器结构中执行间接纹理和凹凸映射，并避免了与在常规着色器中发现的具有缓冲寄存器的大FIFO相关联的问题。在一个实施例中，多个ALU存储器对被同步以形成多个管线到执行着色指令。在另一个实施例中，多个统一着色器被同步并且连接在一起以同时处理着色操作。

摘要： The embodiments of the present invention are a method and apparatus to perform anti-aliasing using multi-sampling on a non-power-of-two pixel grid. Using the present invention with 6 sample multisampling gives the same visual antialiasing quality as 8 samples using a prior art technique but uses less memory. A non-power-of-two equally spaced sample from a conventional grid of size N×N, where N is 12 can be chosen using the present invention. A scan conversion to determine the set of pixels covered by a polygon is performed in two parts. According to one embodiment, the present invention can multiply and divide by “N” in order to multisample an image using samples per pixel chosen from a N×N sub-sample grid, where “N” is not necessarily a power of 2. The present invention performs the divide by “N” step, where the step is achieved using a quick divide by 3 or 12 technique.

摘要： A graphics system including a custom graphics and audio processor produces exciting 2D and 3D graphics and surround sound. The system includes a graphics and audio processor including a 3D graphics pipeline and an audio digital signal processor. Emboss style effects are created using fully pipelined hardware including two distinct dot-product computation units that perform a scaled model view matrix multiply without requiring the Normal input vector and which also compute dot-products between the Binormal and Tangent vectors and a light direction vector in parallel. The resulting texture coordinate displacements are provided to texture mapping hardware that performs a texture mapping operation providing texture combining in one pass. The disclosed pipelined arrangement efficiently provides interesting embossed style image effects such as raised and lowered patterns on surfaces.

摘要： A deflector for use in a hydraulic turbine is adapted to be mounted relative to a vertically extending wall of the draft tube. The deflector has an upstream plate and a downstream plate. The upstream plate is positioned to extend downwardly and outwardly from the wall of the draft tube and the downstream plate is positioned to extend downwardly and inwardly from the upstream plate. The downstream plate has at least one elongated air communication port extending therethrough and adjacent the upstream plate. An air supply inlet portion extends from the wall of the draft tube into the deflector above the elongated air communication port permitting an oxygen containing gas to flow from the air supply inlet portion downwardly through the deflector, out the elongated air communication port and into the water flowing past the downstream plate so as to enhance the dissolved oxygen content of the water.

摘要： A graphics system including a custom graphics and audio processor produces exciting 2D and 3D graphics and surround sound. The system includes a graphics and audio processor including a 3D graphics pipeline and an audio digital signal processor. An additional matrix multiplication computation unit connected in cascade with a modelview matrix computation unit can support a piecewise linear version of skinning for skeletal animation modeling. The normalizer connected between the cascaded matrix multiplication computation units can provide normalization to avoid distorted visualization. The additional matrix multiplication computation unit can be used for applications other than skeletal animation modeling (e.g., environment mapping).
