摘要： A distributed clipping scheme is provided, view frustum culling is distributed in several places in a graphics processing pipeline to simplify hardware implementation and improve performance. In general, many 3D objects are outside viewing frustum. In one embodiment, clipping is performed on these objects with a simple algorithm in the PA module, such as near Z clipping, trivial rejection and trivial acceptance. In one embodiment, the SE and RA modules perform the rest of clipping, such as X, Y and far Z clipping. In one embodiment, the SE module performs clipping by way of computing a initial point of rasterization. In one embodiment, the RA module performs clipping by way of conducting the rendering step of the rasterization process. This approach distributes the complexity in the graphics processing pipeline and makes the design simpler and faster, therefore design complexity, cost and performance may all be improved in hardware implementation.
摘要翻译：提供了一种分布式剪裁方案，视图平滑截尾分布在图形处理流水线的多个位置，以简化硬件实现并提高性能。一般来说，许多3D对象都在观察截面外。在一个实施例中，使用PA模块中的简单算法对这些对象进行限幅，例如接近Z限幅，平凡的拒绝和微不足道的接受。在一个实施例中，SE和RA模块执行其余的剪辑，例如X，Y和远Z限幅。在一个实施例中，SE模块通过计算光栅化的初始点来执行削波。在一个实施例中，RA模块通过进行光栅化处理的渲染步骤来执行裁剪。这种方法在图形处理流水线中分配复杂性，使设计更加简单快捷，因此硬件实现中的设计复杂性，成本和性能都可能得到改善。

摘要： A hierarchical tile-based rasterization method is disclosed. The inventive rasterization algorithm rasterizes pixels in hierarchical rectangles or blocks. The method includes: walking a plurality of tiles of pixels and determining if each tile is valid; breaking each valid tile into a plurality of subtiles and determining if each subtile is valid; breaking each valid subtile into a plurality of quads and determining if each quad is valid; and rendering pixels for each valid quad. These hierarchical levels of block validations are performed in parallel. The inventive rasterization algorithm is further implemented in hardware for better performance.

摘要： A disc drive carrier unit installed on an installation surface of a computer casing is proposed. The installation surface has at least a first positioning piece and a first fixation piece, and both are perpendicular to each other. The disc drive carrier unit has a frame for encompassing and securing a disc drive, a second positioning piece for engaging with the first positioning piece, and at least a second fixation piece for correspondently securing to the first fixation piece. The second positioning piece of the disc drive carrier unit has an engaging function to replace the partial locking design of the conventional technology, for ease of assembly/disassembly and reduction of the assembly cost.
