Abstract:
1. An apparatus for controlling a graphics accelerator, the apparatus comprising: a voltage controller to determine a voltage and a frequency to be implemented with a graphics accelerator so that a frames per second (FPS) of an image to be generated by the graphics accelerator does not exceed a predetermined threshold; and a voltage supplier to supply the determined voltage and frequency to the graphics accelerator wherein the voltage controller comprises: a characteristic value extractor to extract a characteristic value describing the image from graphics data to be provided to the graphics accelerator; a memory to store a relationship between the characteristic value and the voltage and the frequency supplied to the graphics accelerator, the relationship being predetermined based on experimentation or measurement of characteristic values relative to FPS to limit the FPS of the generated image from exceeding the predetermined threshold; and a voltage/frequency detector to determine the voltage and the frequency corresponding to the extracted characteristic value based on the stored relationship.
