Abstract:
A method for controlling a voltage of power supplied to a 3D graphics data processing device and the 3D graphics data processing device using the same are provided to reduce the voltage by using a slack time generated in processing the 3D graphics data of a frame or an object, thereby reducing the consumption of power used in processing the 3D graphics data. A method for controlling a voltage in processing a frame in a pipeline scheme comprises the following steps of: predicting the entire work load of a frame(510); determining the voltage and frequency of power supplied to a pipeline processing unit on the basis of the predicted work load(520); and determining a voltage and a frequency corresponding to a frame received next in consideration of a slack time generated after objects included in the received frame are processed by the pipeline processing unit(530).

Abstract:
PURPOSE: A display device and a method thereof are provided to supply a flowing animation by granting an independent animation effect for an object included in a first and a second window while a first window is switched to a second window. CONSTITUTION: A display unit (130) displays a window including an object. When a screen switch event is sensed, a control unit (120) switches a first window displayed on a screen to a second window and grants an animation effect set in the object. A storage unit (140) stores animation setting information for granting the set animation effect. The animation setting information includes information about an object animation period, an attribute, and a starting offset included in the first and the second windows.

Abstract:
PURPOSE: A voxel visibility based KD(K Dimension) tree configuration apparatus and method thereof are provided to estimate the probability of a node tour using a voxel based matrix. CONSTITUTION: A voxel visibility calculation unit(810) calculates voxel visibility. A KD tree configuration unit(820) divides the voxel into a first voxel unit and a second voxel unit using a surface which minimizes voxel visibility based cost functions. The KD tree configuration unit configures the KD tree by dividing the voxel. A ray tracing unit(830) traces ray for a scene using the configured KD tree.
Abstract:
PURPOSE: A data processing device and a method thereof are provided to hide the memory access latency due to cache miss. CONSTITUTION: A buffer memory unit(120) stores a first input ray data for video rendering in the ray tracing method. A control unit(110) receives first shape data corresponding to the first input ray data from a cache(102). When the first shape data is not stored in the cache, the control unit can receive second shape data while the first shape data is patched to the cache from an external memory. The control unit outputs the first shape data with the first input ray data to a computation device(104).
