摘要： A rasterizer is used with a processor capable of providing raster data indicative of a pattern of pixels to be formed on a display. Each pixel has an attribute represented by a data value. The rasterizer has a replicator connected to form at least two copies of the raster data. A graphics engine is connected to use the at least two copies to store the data values in a memory. An output circuit is connected to use the data values stored in the memory to form the pattern on the display.

摘要： In a specific embodiment, a system for providing video is disclosed, the system having a system bus, which in one embodiment is an Advanced Graphics Port (AGP) bus. The system bus is connected to a data bridge, which is connected to a second and third AGP bus. Each of the AGP busses are connected to graphics processors. The bridge routes data requests from one graphics processor to the second graphics processor without accessing the system AGP bus based upon a memory mapping information stored in a routing table or a register set. In another aspect of the present invention, the bridge responds to initialization requests using attributes that may vary depending on the specific mode of operation. Another aspect of the present invention allows for conversion between various AGP protocol portions.

摘要： A method and apparatus for decompressing compressed data, which includes video data that has been compressed in accordance with the MPEG 2 standard, wherein the processing begins by retrieving components from a non-local memory at a rate that is independent of the rate in which the components were written into the non-local memory. The components include motion vectors and run/level data. As the components are retrieved from memory, the run/level data is used to produce representations of the uncompressed data. As the representations of the uncompressed data are generated, they are processed based on the motion vector data to recapture the uncompressed data. The uncompressed data is then stored in a frame buffer for subsequent display.

摘要： A graphics display command list handler and method requests allocation of memory, such as system memory, in the form of a circular FIFO which stores the display command list as a memory display list (MDL), such as a host memory display list. A processor, such as a graphics processor, communicates a host memory display list read pointer to the host processor to facilitate display list signaling by the graphics processor. The host processor (or other processor) maintains a write pointer which points to a last host memory entry in the display list. The read pointer is maintained by the graphics processor and written back to the host processor.

摘要： A method and apparatus for improved double buffering within a computing system begins when a series of data blocks are received from a central processing unit at a rate independent of a processing rate of a recipient engine. For example, a video graphics circuit receives a series of data blocks representing video frames from the central processing unit at a rate independent of the refresh rate of the display. As the data blocks are received, the video graphics circuit queues commands of the data blocks. Typically, the commands include processing commands and a processing rate synchronize command. To process the data blocks, the co-processor pulls commands from the queued list and processes them to produce recipient data. As the co-processor is producing the recipient data, it is utilizing a first buffer. The co-processor continues to process the commands and storing the results into the first buffer until the processing rate synchronize command is detected. At this point, the co-processor pauses processing of the commands. At the beginning of the next cycle of the processing rate, the recipient data is provided from the first buffer to the recipient engine and the co-processor resumes processing of commands, which relate to another data block. As the co-processor is processing the commands of the second data block, it is utilizing a second buffer to store the processed data, i.e., the second recipient data.

摘要翻译： 一种用于在计算系统内改进双缓冲的方法和装置开始于以与接收机发动机的处理速率无关的速率从中央处理单元接收一系列数据块时开始。 例如，视频图形电路以与显示器的刷新率无关的速率从中央处理单元接收表示视频帧的一系列数据块。 当数据块被接收时，视频图形电路对数据块的命令进行排队。 通常，命令包括处理命令和处理速率同步命令。 为了处理数据块，协处理器从排队列表中提取命令并处理它们以产生接收方数据。 当协处理器产生接收者数据时，它正在利用第一缓冲器。 协处理器继续处理命令并将结果存储到第一缓冲器中，直到检测到处理速率同步命令。 此时，协处理器暂停处理命令。 在处理速率的下一周期的开始，从第一缓冲器向接收者引擎提供接收者数据，并且协处理器恢复与另一个数据块有关的命令的处理。 当协处理器正在处理第二数据块的命令时，它利用第二缓冲器来存储经处理的数据，即第二接收者数据。

摘要： A method and apparatus for improved concurrency within a video graphics process by generating culling information from geometry information. The geometry information corresponds to an image to be rendered, and the culling information indicates the triangles of the objects of the image that are in a front-facing or back-facing position. Having generated the culling information, set-up information is generated therefrom. The set-up information provides rendering data for the triangles of the object of the image being rendered. Next, pixel data is generated for a triangle based on the set-up information. To improve the concurrency, the queuing and the retrieval of the culling information and the set-up information from non-local memory are controlled such that the generating of the culling information, the set-up information, and the pixel data is done with improved concurrency.
