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 mapping a linear address to a tiled address that reduces latency between retrieval of pages of data is accomplished when a video graphics processor receives a linear address from the central processing unit and determines whether the linear address is referencing a tiled surface, which is one of up to four portions of the memory. If so, the video graphics processor obtains parameters of the tiled surface. Having obtained the parameters, the video graphics processor determines a normalized linear address based on at least one of the parameters and the linear address. Having done this, the video graphics processor determines a band pointer of the tiled surface based on at least one of the parameters, the normalized linear address and a modular function. In essence, the band pointer points to a normalized initial address of a band of a tiled surface, which includes a plurality of bands. Having obtained the band pointer, the video graphics processor then determines a linear band offset based on the band pointer and at least one of the parameters. Next, a tiled band offset is determined based on the linear band offset. Finally, the tiled address is determined based on the tiled band offset, the band pointer, and at least one of the parameters.

摘要： A method and apparatus for storing sequential data words associated with a block of data in a non-linear manner within the data block is taught such that any row or column associated with the data block may be accessed using a burst access. A row, or column of data accessed by a burst frees up instruction bandwidth of a video controller. In particular, it is assured that each row and column of data associated with the data block has at least one sequential pair of data words associated with it. By assuring at least one sequential pair of data words, it is possible to issue a burst request for a minimum of two words of data with each row access, or column access of the video controller.

摘要： An apparatus and method for processing pixel depth information eliminates stalling of data in a pixel pipeline, by performing late Z processing for one or more pixels currently in the pixel pipeline and early Z processing for one or more pixels entering the pixel pipeline. The apparatus and method also includes determining whether the late Z processing for the one or more pixels currently in the pixel pipeline has been completed. The apparatus and method also includes solely performing early Z processing for subsequent pixels entering the pixel pipeline responsive to determining that late Z processing for the one or more pixels currently in the pixel pipeline has been completed. The methods and apparatus, facilitates concurrent processing of early and late Z data to avoid flushing portions of the pixel pipeline.
