METHOD FOR CONTROLLING VOLTAGE USED TO PROCESSING 3 DIMENSIONAL GRAPHICS DATA AND APPARATUS USING IT

摘要

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).
