Abstract: Provided is a decompression apparatus and method thereof for decompressing rendering data. The decompression apparatus includes a data parsing unit configured to acquire a control component and a texture component from compressed input data including rendering information of an object, a decompression controller configured to allocate the control component to a control unit, wherein the control unit extracts a control command from the control component, and a logic calculation unit configured to, based on the control command, restore texture data of the object from the texture component.

Abstract: A method and apparatus of processing rendering data are disclosed. The method of processing rendering data includes comparing texture information of a first tile with texture information of a second tile that is rendered after the first tile, selecting at least one piece of texture data from pieces of texture data of the first tile according to a frequency of use of the at least one piece of texture data for rendering the second tile, and changing the selected at least one piece of texture data into another piece of texture data. When an image is rendered, the method and apparatus may more efficiently use resources.
