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 include processing which allows a graphics controller to extend its memory by receiving a client address and determining which of a plurality of system bus interfaces (e.g., AGP, PCI, ISA) is enabled. When a first type of system bus interface is enabled (e.g., PCI, ISA), a first system bus table index is generated based on the client address. The first system bus table index is used to access a first system bus table to retrieve a physical address of memory. The processing continues by obtaining data from the memory, wherein the data is stored at the physical address.

摘要： A configurable register method and structure included configuration logic to form a register value. A data bridge system, for connecting an interface of a computer system to a plurality of application-specific integrated circuits (ASIC), has a data bridge operatively coupled between the computer interface and the plurality of ASICs that employs the configurable registers. The data bridge has a read only memory for storing at least the initial values and mask values for each ASIC of the plurality of ASICs. The data bridge upon initialization forms base address registers and other configuration data that are queried by the computer system. When the ASICs are graphic processors, the initial values and the mask values stored in the read only memory define the base address registers in the data bridge as a function of the configuration requirements of the graphic processors. The base address registers are thus programmable as a function of the initial values and mask values in the read only memory. The read only memory is coupled to the data bridge.
