Abstract: A texture processing unit includes a controller configured to obtain a texture coordinate and spatial frequency information for each channel of a texture corresponding to the texture coordinate, and determine a filtering control signal for each channel of the texture based on the spatial frequency information for each channel, and a texture filter configured to perform filtering for each channel of the texture according to the filtering control signal for each corresponding channel.

Abstract: Provided are a method and an apparatus for transforming coordinates of pixels representing boundary points of an object on a cube map, when pixels respectively correspond to different faces of a cube map. Distances between the boundary pixels may be calculated by using the transformed coordinates. Based on the on the calculated distances, a level of detail (LOD) for texturing the cube map of the pixels may be determined.

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 texture processor includes: a texture cache configured to store textures; a controller configured to determine a texture address corresponding to a requested texture among the stored textures and read a texture corresponding to the texture address from the texture cache; a format converter configured to convert a format of the read texture into another format, based on a degree of texture precision required by a graphics processing unit (GPU); and a texture filter configured to perform texture filtering using the read texture having its format converted into the another format.

Abstract: Provided are a graphics pipeline method and apparatus. For each of plural screen pixels, locations of one or more sampling are determined based on a set pattern to modify an image to be rendered. A pixel corresponding to a set primitive is generated at a determined location of a sampling point, of the one or more sampling points. The image is rendered using the generated pixel.
