Embodiments of the invention provide assigning two different class identifiers to a device to allow loading to an operating system as different devices. The device may be a graphics device. The graphics device may be integrated in various configurations, including but not limited to a central processing unit, chipset and so forth. The processor or chipset may be associated with a first identifier associated with a graphics processor and a second device identifier that enables the processor or chipset as a co-processor.

System co-processor

An embodiment of the present invention is a technique to interface a display card through an interface connector. A video output device on the display card generates digital video output signals from a graphics chipset on a motherboard. The card is plugged into an interface connector on the motherboard. The interface connector is compatible with a first interface standard. The video output device is compatible to a second interface standard. A card detector is coupled to the video output device and the interface connector to enable the video output device if the graphics chip set supports the video output device.

Interfacing a digital display card through PCI express connector

According to one aspect of the invention, a method is provided in which a first clock signal is generated. A second clock signal is derived from the first clock signal. The second clock signal is delayed relative to the first clock signal by a first delay period by a delay locked loop (DLL) circuit. The second clock signal is used to latch incoming data from a memory device.

Method, apparatus, and system for high speed data transfer using programmable DLL without using strobes for reads and writes

According to one aspect of the invention, a method is provided in which a write strobe signal is generated to latch output data into a memory unit that comprises one or more dual data rate synchronous dynamic random access memory (DDR-SDRAM) devices. The write strobe signal has an edge transition at approximately the center of a data window corresponding to the output data. A first receive clock signal is delayed by a first delay period using a delay locked loop (DLL) circuit to generate a first delayed receive clock signal. The first delayed receive clock signal is used to latch incoming data from the memory unit.
