摘要： A stand-alone graphics workstation including a digital computer host and a graphics processing subsystem is disclosed. Address data relating to the graphics subsystem components is mapped into the host system virtual memory. The application processes residing in the host are thereby able to communicate directly with the graphics subsystem components, as, e.g. the structure memory, without the need of a direct memory access hardware arrangement or device drivers.

摘要： A method for operating a computer graphics system to build custom nodes containing commands and data information that is stored in a data structure in the graphics subsystem. A host processor calls routines which build the custome nodes. A structure walker traverses the data structure and extracts the information from the data structure to pass it to the graphics subsystem for display. The use of custom nodes increases the flexibility of advanced graphics data structures bny allowing the creation of other data structures during execution of a first data structure.

摘要： A method and apparatus for operating a computer graphics system to perform a conditional test on a node in a graphics data structure during the traversal of the graphics data structure by a structure walker. The graphics system is operated to manipulate data contained in a memory to define a value for an operand that is to be tested. The system accesses the operand from the memory. A structure walker performs a test on the value of the operand during traversal of the graphics data structure. Depending upon the result of the test, the structure walker traverses one of several paths in the graphics data structure to create a graphics display.

摘要： A host system executes one or more application programs which results in graphic data structures. These graphic data structures are then continuously and asynchronously traversed. Traversal requests by competing application programs are scheduled and performed so that each application views the graphics processing as its own. The traversal and ordering of traversal requests provide efficient use of resources for multiple application programs.

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： 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.
摘要翻译：本发明通过在分箱和渲染阶段之间提供bin存储器的自动管理来优化区域渲染期间的图形性能。本发明的实施例提供了一种机制，通过该机制，虚拟机和渲染器自动共享物理存储器页面池，以便构建bin缓冲器并在渲染后使用它们。这样做的方式是，可以将多个分箱的场景同时排队，除非在特殊情况下不需要软件干预。因此消除了对区域渲染bin缓冲存储器的软件管理的需要。用于分档和渲染的多个场景也可以排队等待，无需软件干预。

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.
摘要翻译：一种深度写入禁止装置和方法，用于控制从区域渲染系统中的深度缓存到相应的深度缓冲区的撤离，例如深度值。当深度写入禁止电路被使能时，防止从深度缓存（通常在渲染下一个区域期间发生）到深度缓冲区的驱逐。特别地，一旦深度缓冲器被初始化（即清除）到场景开始处的恒定值，则不需要读取深度缓冲器。深度缓存处理每个区域内的中间深度读取和写入。由于在呈现场景后不需要内存驻留深度缓冲区，因此不需要写入。因此，在每个区域呈现之后，区域的最终深度值因此可被丢弃（即，而不是写入深度缓冲区）。

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.
摘要翻译：本发明的实施例提供一种分割顶点缓冲器，其中每个顶点的数据在平行顶点缓冲器之间分割。第一个缓冲区包含顶点X和Y数据，而第二个并行缓冲区包含顶点数据的其余部分。给定分割顶点缓冲区，现在允许硬件分箱引擎读取和缓存顶点屏幕X和Y数据。特别是考虑到索引顶点参考之间通常具有高水平的时间一致性，大块顶点屏幕空间X和Y的读取和高速缓存导致硬件分档输入的存储器带宽的较低和高效利用。因此，本发明的实施例减少了硬件分组存储器带宽需求并提高了存储器利用率。
