    摘要： In a graphics pipeline, a rasterizer circuit generates fragments for an image having multiple surfaces that have been tessellated into primitive objects, such as triangles. First and second fragments are associated with the same pixel. A merge buffer merges the first fragment with the second fragment when the two fragments belong to the same tessellated surface, the first fragment's primitive is adjacent to the second fragment's primitive, both fragments face either toward or away from the viewer, and the first and second fragment are sufficiently similar that merging is unlikely to introduce visually objectionable artifacts. A frame buffer receives fragments from the merge buffer, stores the fragments, combines the fragments into pixels, and outputs the pixels to a display.

    摘要： A computer graphics system maps textures to displayed anti-aliased images with surfaces defined at oblique angles to the viewer. A circular pixel filter is projected onto a texture map to define an elliptical footprint in that texture map. The elliptical footprint has a major axis. Sample points are determined on a line in the footprint that closely approximates the major axis. These sample points are mapped to levels of detail and locations within a mip-map. Using a space-invariant filter, a texture value is computed for each sample point using data from one or more texture maps within the mip-map. These texture values for the sample points are post-filtered using a Gaussian filter function and summed to produce a final texture value. Blending the final texture with other characteristics of the pixel a produces the pixel data that are displayed on a display screen.

    摘要： A plurality of computer systems is operable to execute an application. A power consumption is determined for a first computer system if the first computer system were to execute the application, and a power consumption is determined for at least one other computer system if the second computer system were to execute the application. One of the computer systems is selected to execute the application based on the determined power consumptions.

    摘要： A computer system uses a prefetch prediction model having energy usage parameters to predict the impact of prefetching specified files on the system's energy usage. A prefetch prediction engine utilizes the prefetch prediction model to evaluate the specified files with respect to prefetch criteria, including energy efficiency prefetch criteria, and generates a prefetch decision with respect to each file of the specified files. For each specified file for which the prefetch prediction engine generates an affirmative prefetch decision, an identifying entry is stored in a queue. The computer system fetches files identified by entries in the queue, although some or all of the entries in the queue at any one time may be deleted if it is determined that the identified files are no longer likely to be needed by the computer system.

    摘要： Power system components are mapped using a controller and a data collection system. The controller is operable to transmit a first power system component ID for the first power system component to a second power system component, wherein the second power system component receives power from the first power system component. The data collection system is operable to receive from the second power system component the first power system component ID and a second power system component ID for the second power system component. The data collection system is further operable to associate the first power system component with the second power system component based on the received IDs.

    摘要： Load demands in a power system are managed by determining whether load demands on one or more power system components need to be varied. If the load demands need to be varied, new load demands to be placed on the power system components are determined. The load demands on the power system components are controlled such that the load demands are substantially equal to the new load demands.
