A rendering method includes receiving an input including pixel pattern information of a device configured to display a rendered image, generating a pixel pattern of the rendered image using the received input indicating pixel pattern information, and outputting a pixel value of the rendered image into a frame buffer using the generated pixel pattern.

Rendering method, rendering apparatus, and electronic apparatus

A device for processing image data is disclosed. The device may determine a dominant texture with respect to each of a plurality of regions constituting an image. The device may group in a same group, from among the plurality of regions, regions in which the determined dominant texture is the same, and process allocated image data according to a result of grouping.

Method and device for processing image data

A control device for cache bypass includes: an information acquirer configured to acquire information about pixels on a screen space and a texture to be mapped to the pixels; and a controller configured to determine a scale factor, by using the acquired information, and to control texture data corresponding to the texture to bypass a cache based on the scale factor, wherein the scale factor is a ratio of a size of the texture to a size of the pixels.

Graphics processing unit and method of controlling cache bypass thereof

Provided are methods and apparatuses for adjusting the processing sequence of draw commands for rendering images. The rendering method including determining, at a processing sequence determiner, previous draw commands that are identical to current draw commands; de-termining a processing sequence of the current draw commands based on depth information of the determined previous draw commands; and performing a Z-test on the current draw commands based on the processing sequence, and performing shading based on a result of the Z-test.

Apparatus and method of rendering frame by adjusting processing sequence of draw commands

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.

Graphics pipeline method and apparatus

A texture cache architecture includes a first texture cache to store compressed texel data and a second texture cache to store decompressed texel data. A controller schedules accesses to access texel data from the first or second texture cache. The second texture cache permits decompressed texel data to be reused for more than one texel access request.

Efficient low-power texture cache architecture

A tessellation method and apparatus are provided, where the tessellation method includes receiving a first value that is calculated in performing tessellation, the first value being a first floating-point real number represented by a first exponent and a first mantissa; determining a second precision of the first mantissa on the basis of a value of the first exponent and a first precision; and adjusting the first mantissa to have the second precision.

Tessellation apparatus and method

A method and device for processing graphics data include generating primitives including objects in an image, classifying tiles dividing the image into scalable tile groups, generating a coverage pattern identifying primitives that are covered on tiles included in each scalable tile group, generating a bin stream including the coverage pattern corresponding to the each scalable tile groups, and performing rendering for each tile of the tiles using the bin stream.

Graphics processing device and operating method for performing tile-based graphics processing using the same

A texture cache architecture facilitates access of compressed texture data in non-power of two formats, such as the Adaptive Scalable Texture Compression (ASTC) codec. In one implementation, the texture cache architecture includes a controller, a first buffer, a second buffer, and a texture decompressor. A first buffer stores one or more blocks of compressed texel data fetched, in response to a first request, from a first texture cache, where the one or more blocks of compressed texel data including at least requested texel data. The second buffer stores decompressed one or more blocks of compressed texel data and provides the decompressed requested texel data as output to a second texture cache. The one or more blocks of compressed texel data stored by the first buffer includes second texel data in addition to the requested texel data.

Cache architecture for efficiently accessing texture data using buffers

Signal processing may include determining a first component common to a first input signal and a second input signal and extracting the first component from at least one of the first input signal or the second input signal, a second component from the first input signal, and a second component from the second input signal. The second component of the first input signal may be different from the second component of the second input signal. An operation may be performed using the extracted, second components. The first component may be combined with a result of the operation.

System and method to process signals having a common component

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.
