  • Patent number: 8139058
    Abstract: 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.

  • Patent number: 7746355
    Abstract: 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.

  • Patent number: 7523529
    Abstract: The present invention proposes an engagement mechanism employed in a first assembly part and a cooperating second assembly part. The engagement mechanism comprises a pivot member assembled in the first assembly part; and an elastic member having a double-wedged surface at an endmost portion thereof which extends outwardly from the projecting portion of the first assembly part. The elastic member is employed to provide an elastic force of maintaining the projecting portion extending outwardly from the first assembly part to engage with the second assembly part. The present invention, via the design of the double-wedged surface of the projecting portion, facilitates easy engagement or disengagement of the engagement mechanism, and overcomes the problem of having to provide extra disengagement arrangement in the prior art.

  • Patent number: 7218513
    Abstract: 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.
