摘要： A texture map 1 for use in graphics processing is encoded by first subdividing the texture map 1 into a plurality of texture element blocks 2. The texture data elements in each texel block to be encoded are then divided into different partitions (sub-sets) 10, 11, 12 within the block. The partitioned block 2 is then encoded in a compressed form as an encoded texture data block 13. Each encoded block is partitioned using a partitioning pattern generation function to generate the partitioning patterns. The partitioning pattern generation function sorts the texture data elements of the block into respective partitions based on their respective positions within the block. To do this the partitioning pattern generation function generates a series of sawtooth waves at various angles, phases and frequencies across the block of texture data elements to be encoded.

摘要： Each block of texture data elements is encoded as a block of texture data. The encoding process includes determining for each block of texture data elements whether the set of texture data elements of the block all have sufficiently similar data values. If they do, the extent of a region within the texture including the block in which every texture data element has sufficiently similar data values is then determined, and an encoded texture data block to represent the block of texture data elements that indicates that the block specifies a region within the texture in which every texture data element is to be allocated the same data value when decoded, and that includes data indicating the constant data value for the block and data indicating the extent of the region within the texture that the block relates to, is generated.

摘要： Each block of texture data elements is encoded as a block of texture data that includes a set of integer values to be used to generate a set of base data values for the block, and a set of index values indicating how to use the base data values to generate data values for the texture data elements that the block represents. The integer values and the index values are both encoded in an encoded texture data block using a combination of base-n values, where n is greater than two, and base-2 values. Predefined bit representations are used to represent plural base-n values (n>2) collectively, and the bits of the bit representations representing the base-n values are interleaved with bits representing the base-2 values in the encoded texture data block.

摘要： A graphics processing unit 2 includes a texture pipeline 6 having a first pipeline portion 18 and a second pipeline portion 20. A subject instruction within the first pipeline portion 18 is recirculated within the first pipeline portion 18 until descriptor data to be loaded from a memory 4 by that subject instruction has been cached within a shared descriptor cache 22. When the descriptor has been stored within the shared descriptor cache 22, then the subject instruction is passed to the second pipeline portion 20 where further processing operations are performed and the subject instruction recirculated until those further processing operations have completed. The descriptor data is locked within the shared descriptor cache 22 until there are no pending subject instructions within the texture pipeline 6 which required to use that descriptor data.

摘要： When encoding a set of texture data elements 30 for use in a graphics processing system, the direction along which the data values of the set of texture data elements in question exhibit the greatest variance in the color space is estimated by using one or more infinite planes 41 to divide the texture data elements in the color space. For each such plane, texture data element values on each side of the plane are added up to give respective sum points 48, 49, and the vector 50 between these two sum points determined. The direction in the data space of one of the determined vectors 50 is then used to derive endpoint color values to use when encoding the set of texture data elements.
