摘要:
A method of displaying graphics data is described. The method involves accessing the graphics data in a memory subsystem associated with one graphics subsystem. The graphics data is transmitted to a second graphics subsystem, where it is displayed on a monitor coupled to the second graphics subsystem.

A method for managing host system power consumption is provided. The host system includes host memory and external memory. The method initiates with providing a processor in communication with a memory chip over a bus. The memory chip is external memory. Then, a usage measurement of the external memory is determined. If the usage measurement is below a threshold value, the method includes copying data from the memory chip to the host memory and terminating power to the memory chip. In one embodiment, the power is terminated to at least one bank of memory in the memory chip. In another embodiment, an amount of reduction of the external memory can be determined rather than a usage measurement. In yet another embodiment, an address map is reconfigured in order to maintain a contiguous configuration. A graphical user interface and a memory chip are provided also.

Method and apparatus for display image adjustment is described. More particularly, handles associated with polygon vertices of a polygon rendered image are provided as a graphical user interface (GUI). These handles may be selected and moved by a user with a cursor pointing device to adjust a displayed image for keystoning, among other types of distortion. This GUI allows a user to adjust a projected image for position of a projector with respect to imaging surface, as well as for imaging surface contour, where such contour may be at least substantially planar, cylindrical, or spherical and where such contour may comprise multiple imaging surfaces. This advantageously may be done without special optics or special equipment. An original image is used as texture for rendering polygons, where the image is applied to the rendered polygons.

A method and system for coordinated data execution in a computer system. The system includes a first graphics processor coupled to a first memory and a second graphics processor coupled to a second memory. A graphics bus is configured to couple the first graphics processor and the second graphics processor. The first graphics processor and the second graphics processor are configured for coordinated data execution via communication across the graphics bus.

摘要:
A computer system including a processor, a display, and a graphics unit coupled between the processor and the display, in which the processor is configured to perform multi-display operations which generate multiple frames of display data for simultaneous display, and a graphics unit for use in such a system. Typically, the graphics unit includes graphics memory that includes at least two frame buffers, and the processor operates as if it were independently asserting multiple streams of display data to multiple frame buffers for driving multiple displays independently. Another aspect of the invention is a system that displays data from a frame buffer on a screen. The frame buffer holds data indicative of a virtual desktop that is larger than can be displayed on the screen or available portion thereof, the system can display on the screen any of a number of different subsets of the frame buffer data, each subset indicative of a different portal of the desktop, and the system includes a processor including texture processing circuitry operable to filter a subset of the frame buffer data that is indicative of a portal to be displayed.

Method and apparatus to make code more difficult to reverse engineer is described. Inert instructions are inserted between instructions within a program. The inert instructions may perform logic operations with the net effect of not changing an argument. Furthermore, the inserted inert instructions may be repositioned within the program to further obfuscate the desired function of the program, making the code more difficult to reverse engineer.

摘要:
A system and method for providing a dedicated interface between two or more graphics adapters installed on a motherboard. Surplus signals within an interface conforming to an interface specification are used to create the dedicated interface. The dedicated interface may connect the two or more graphics adapters using connectors via an interface device. Alternatively the dedicated interface may directly connect the two or more graphics adapters using dedicated connectors or a portion of the connectors coupled through conductive traces integrated onto the motherboard.
