Abstract: A method and a device for texture filtering include determining an upper mipmap and a lower mipmap based on a level of detail (LOD) value corresponding to a quad, obtaining first color values corresponding to the upper mipmap, obtaining second color values corresponding to the lower mipmap, and obtaining third color values of the pixels of the quad by using linear interpolation, based on the obtained first and second color values.

Abstract: A cache memory apparatus including a cache memory including a bank, a partition configuration unit configured to divide the cache memory into partitions by allocating the bank to a texture among textures for rendering, and a controller configured to receive a partition ID, of texture data requested by a device that performs the rendering, determine whether the requested texture data is stored in a partition corresponding to the partition ID among the plurality of partitions, and output the requested texture data to the device based on a result of the determination.

Abstract: A method of determining a level of detail (LOD) for a texturing includes: acquiring texture coordinate data on pixels included in an upper block; determining a reference quad among quads included in the upper block; determining a similarity between the determined reference quad and the upper block using texture coordinates of the determined reference quad and the upper block; and determining LODs of remaining quads among the quads included in the upper block to be the same as an LOD of the determined reference quad in response to the determining of the similarity including determining that the determined reference quad and the upper block are similar.

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.
