Abstract: A texture processing apparatus for performing filtering by using a plurality of textures. A controller is configured to obtain a first texel value from a memory, in which the first texel value is based on a computed first texel offset value. The previously-computed first texel offset value may be used as a second texel offset value to obtain a second texel value of a second texture if a same texture address is input with respect to the first texture and the second texture that are continuously input. A texture filter is configured to perform filtering based on the obtained texel value of the first texture and the texel value of the second texture.

Abstract: A method and apparatus for processing a texture are provided. The method of processing the texture includes acquiring a texture address corresponding to a pixel address and frequency information of the texture, determining a number of texels to be used for texture filtering according to the frequency information of the texture, reading texel values corresponding to the determined number of texels based on the texture address, and performing the texture filtering by using the read texel values.

Abstract: A method and apparatus for providing shared caches. A cache memory system may be operated in a first mode or a second mode. When the cache memory system is operated in the first mode, a first cache and a second cache of the cache memory system may be operated independently. When the cache memory system is operated in the second mode, the first cache and the second cache may be shared. In the second mode, at least one bit may overlap tag bits and set index bits among bits of a memory address.
