Provided are apparatuses and methods for rendering. The methods analyze draw commands and graphics states, generate hierarchical graphics states from the graphics states based on a graphics state common to the draw commands, and perform rendering of an image frame based on the hierarchical graphics states. The apparatuses use a hierarchical state generator and a graphics processing unit (GPU) to perform the rendering method.

Rendering apparatus and method

Provided is a method and apparatus of selecting a preemption technique for a computation unit included in a processor to execute a second task before the at least one computation unit finishes executing a first task. The method includes receiving a preemption request, predicting a cost of preemption techniques based on a progress of the first task until receipt of the preemption request, and selecting one of the preemption techniques based on the predicted cost.

Method and apparatus for selecting preemption technique

A power consumption control apparatus includes a resource selecting unit configured to select resources, whose power consumption levels are to be determined, from among resources of a graphic processing unit (GPU), a resource use information acquiring unit configured to determine whether the selected resources are used from a code block which is all or part of a program executed using the GPU, and a power consumption controlling unit configured to determine a power consumption level of the selected resource based on a determination result of the resource information acquiring unit and to control the power consumption level of the selected resources based on a determined power consumption level of the selected resources.
