Abstract: A fixed rate compressor is used to perform variable rate texture compression. A texture image is accessed. A block size used to compress the image is automatically varied over the image to achieve variable rate texture compression. The block size may be selected to reduce the compressed texture image size and adapted in local regions of the texture image based on quality considerations, such as a quality condition that an error for each block be less that a threshold error. The restriction on block size and block types may be selected to perform decompression with hardware conventionally used to perform decompression of fixed-rate blocks. The quality condition may be user-selectable by a user input to provide additional control over the tradeoffs between quality and compression.

Abstract: 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.

Abstract: In a graphics processing system pixel data and vertex coordinate information from a previous frame is buffered and provided to the current frame. A decision is made in the current frame whether pixel data from the previous frame may be reused. In one implementation if the speed of pixels in a tile is less than a quasi-static speed threshold a decision is made whether or not to reuse a fraction of pixels from the previous frame.

Abstract: Graphics processing is performed in which a decision is made in individual tiles whether or not to sample at a reduced sampling rate. A sampling pattern is selected from a set of sampling patterns having the same reduced sampling rate. The sampling pattern is dithered over a set of frames to reduce the visual appearance of visual artifacts via temporal color averaging.

Abstract: A graphics system includes a reconstruction unit that utilizes higher order polynomials, such as cubic splines, to reconstruct missing pixel data. The computational work to perform interpolation with higher order polynomials, such as cubic splines, is reduced by pre-calculating weights for each sparse sample pattern. The pre-calculated weights may be stored as stencils and used during runtime to perform interpolation.

Abstract: A graphics system supports variable rate compression and decompression of texture data and color data. An individual block of data is analyzed to determine a compression data type from a plurality of different compression data types having different compression lengths. The compression data types may include a compression data type for a block having a constant (flat) pixel value over n×n pixels, compression data type in which a subset of 3 or 4 values represents a plane or gradient, and wavelet or other compression type to represent higher frequency content. Additionally, metadata indexing provides information to map between an uncompressed address to a compressed address. To reduce the storage requirement, the metadata indexing permits two or more duplicate data blocks to reference the same piece of compressed data.

Abstract: 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.

Abstract: An apparatus, system and method is provided to determine a motion of pixels in local regions of a scene, classify the motion into a speed category, and make decisions on how to render blocks of pixels. In one implementation the motion in a tile is classified into at least three different speed regimes. If the pixels in a tile are in a quasi-static speed regime, a determination is made whether or not to reuse a fraction of pixels from the previous frame. If the pixels are determined to be in a high speed regime, a decision is made whether or not a sampling rate may be reduced.
