Embodiment Construction

[0027] As is conventional in the field of the inventive concept, the embodiments are described and shown in the figures in terms of functional blocks, units and / or modules. Those skilled in the art will appreciate that these blocks, units and / or modules are implemented by electronic (or optical) circuits (such as logic circuits, discrete components, microprocessors, hard wire circuits, memory elements, wire connections, etc.) are physically implemented. Where the blocks, units and / or modules are implemented by a microprocessor or the like, they can be programmed using software (e.g., microcode) to perform the various functions discussed herein, and can be programmed by firmware and / or software Optionally drive them. Alternatively, each block, unit and / or module can be realized by dedicated hardware, or can be realized as dedicated hardware for performing some functions and a processor for performing other functions (for example, one or more programmed combination of micropro...

Abstract

The present invention provides a texture processing method and unit. The texture processing unit includes: a controller configured to determine a first calculator that performs a calculation on a first mipmap and a second calculator that performs a calculation on a second mipmap, based on a level of detail (LOD) weight indicating influences of the first mipmap and the second mipmap on texture filtering, the influences being based on an LOD value of graphics; and a texture filter configured to perform the texture filtering by using the first calculator and the second calculator, wherein a calculation precision of the first calculator is different from a calculation precision of the second calculator.

Description

[0001] This application claims priority from Korean Patent Application No. 10-2016-0145215 filed with the Korean Intellectual Property Office on November 2, 2016, the disclosure of which is hereby incorporated by reference in its entirety. technical field [0002] At least some example embodiments of inventive concepts relate to a texture processing method and unit. Background technique [0003] Texturing or texture mapping is used to obtain more realistic images in three-dimensional (3D) graphics systems. Texturing or texture mapping refers to a method performed by a texture processing unit for defining a two-dimensional (2D) image on a surface of a 3D object in order to apply a texture to the surface of the 3D object. The term "texture" refers to an image applied to an object. In texture mapping, a set of bitmap images consisting of a base texture and its reduced-sized texture is called a mipmap. [0004] Since the number of thinning maps stored in the texture processing...
