    摘要: Similar, contiguous primitives are stored as a single primitive in zone rendering bins. A primitive packet used in the bin is allowed to vary in length and the currently open type of primitive is recorded on a per-bin basis. A special code is used to specify a variable number of subsequent indices. With this mechanism, the hardware is able to start outputting and replicating primitive commands into bin lists on the fly without requiring the buffering of the entire primitive. Given the variable nature of the primitive instruction, multiple similar/sequential primitives can be concatenated using a single primitive command header.

    摘要: A method, apparatus, and system to concurrently render independent images for display on one or more display devices. In an embodiment, a graphics-rendering engine concurrently renders independent images for display on multiple display devices. A time allocator arbitrates the concurrent use of the graphics-rendering engine between each independent image being rendered.

    摘要: The present invention optimizes graphics performance during zone rendering by providing an automatic management of bin memory between the binning and rendering phases. Embodiments of the present invention provide a mechanism by which the binner and renderer automatically share a pool of physical memory pages in order to build bin buffers and recycle them after they have been used in rendering. This is performed in such a fashion that multiple binned scenes can be queued up concurrently, with no requirement for software intervention except under exceptional conditions. The need for software management of zone rendering bin buffer memory is thus eliminated. Multiple scenes for binning and rendering can also be queued without software intervention.

    摘要: A depth write disable apparatus and method for controlling evictions, such as depth values, from a depth cache to a corresponding depth buffer in a zone rendering system. When the depth write disable circuitry is enabled, evictions from the depth cache (as which typically occur during the rendering of the next zone) to the depth buffer are prevented. In particular, once the depth buffer is initialized (i.e. cleared) to a constant value at the beginning of a scene, the depth buffer does not need to be read. The depth cache handles intermediate depth reads and writes within each zone. Since the memory resident depth buffer is not required after a scene is rendered, it never needs to be written. The final depth values for a zone can thus be discarded (i.e., rather than written to the depth buffer) after each zone is rendering.

    摘要: Embodiments of the present invention provide a split vertex buffer where the data for each vertex is split between parallel vertex buffers. The first buffer contains vertex X and Y data, while the second parallel buffer contains the remainder of the vertex data. Given the split vertex buffers, the hardware binning-engine is now permitted to read and cache only vertex screen X and Y data. Especially given a typically high level of temporal coherency between indexed vertex references, the reading and caching of large parcels of vertex screen-space X and Y leads to lower and highly efficient utilization of memory bandwidth for hardware binning input. Embodiments of the present invention thus reduce the hardware binning memory bandwidth requirements and improve memory utilization.
