摘要： A method, system and computer program product for dynamically composing processor cores to form logical processors. Processor cores are composable in that the processor cores are dynamically allocated to form a logical processor to handle a change in the operating status. Once a change in the operating status is detected, a mechanism may be triggered to recompose one or more processor cores into a logical processor to handle the change in the operating status. An analysis may be performed as to how one or more processor cores should be recomposed to handle the change in the operating status. After the analysis, the one or more processor cores are recomposed into the logical processor to handle the change in the operating status. By dynamically allocating the processor cores to handle the change in the operating status, performance and power efficiency is improved.

摘要： An interpolation unit, such as may be found in a texture unit or texture sampler, may be used utilized to perform general purpose mathematical computations such as dot products. This enables some general purpose computations and operations to be offloaded from a central processing unit to an interpolation unit. The interpolation unit may use linear interpolators in order to perform the dot product calculations.

摘要： Methods and systems to determine view cell occlusion, including to project objects of a 3-dimensional graphics environment to a 2-dimensional image plane with respect to the view point, to reduce sizes of corresponding object images, to generate an occluder map from the reduced-size object images, to compare at least a portion of the object images to the occluder map, and to identify an object as occluded with respect to the view cell when pixel depth values of the object image are greater than corresponding pixel depth values of the occluder map. Methods and systems to reduce an object image size include methods and systems to nullify pixel depth values within a radius of an edge pixel, and to determine the radius as a distance from the edge pixel to a second pixel so that a line between the view point and the second pixel is parallel with one or more of a line and a plane that is tangential to a sphere enclosing the view cell and a point on the object that corresponds to the edge pixel.
