Abstract: A graphics device delivers a graphics address to a graphics memory switch that includes a graphics random access memory translator and a graphics memory page table. The graphics memory address is delivered to the graphics memory switch via a point-to-point, packet based interconnect. The graphics memory switch generates a physical system memory address and delivers the physical address to a root complex. The physical system memory address is delivered to the root complex via a point-to-point, packet based interconnect.

Abstract: Methods and apparatus for use with AGP-capable computer systems are disclosed. Since each AGP-capable chipset can have a unique range of graphics port aperture sizes that it supports, current graphics port aperture drivers are chipset-specific, with hard-coded tables of supported graphics aperture sizes. Described herein is a driver that dynamically ascertains the range of supported graphics aperture port sizes for an attached AGP-capable chipset, thus allowing this driver to be ported between different chipsets without manual reconfiguration and recompiling. The method employed in the driver sends one or more test aperture size values to a register resident in the chipset, and then reads what is written to see if the chipset changed any of the bits of the test value. The method infers supported sizes from examining which, if any bits, were changed by the chipset.

Abstract: A nuclear camera is provided with an open and flexible software architecture which enables users to readily understand, modify, and exchange data files. In a constructed embodiment the software architecture utilizes xml files which can be defined and read by a user using readily available tools and viewers. Both control data and image data can be formatted in this manner. An illustrated software architecture contains a directory of manufacturer-supplied xml control files, and a directory of user modified or created xml control files. This software architecture enables users to exchange protocol and image information over conventional communications networks such as the Internet.
