摘要： 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.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： An image processing method includes receiving a bitstream comprising a first encoding unit and a second encoding unit; acquiring from the bitstream a reference value for decoding of the first coding unit, a weight value for performing interpolation using the reference value to determine one or more sample values, and an index indicating one of the one or more sample values; decoding the first encoding unit using the index and a result of interpolation performed using the reference value and the weight value; and decoding the second encoding unit from the bitstream using the interpolation result used in the decoding of the first encoding unit.
