Abstract: A graphics texture data encoding arrangement in which the texels in a texel block 30 to be encoded are divided into different partitions within the block. A reference partitioning pattern for a texel block to be encoded is generated by using a partitioning function 32 to partition the data values for the texels into a number of data value partitions, and then sorting the individual texels in the texel block into respective partitions 33 based on their values. A set of predefined partitioning patterns 35 that the encoding scheme supports is then compared 36 to the generated reference partitioning pattern. The predefined partitioning pattern that best matches 39 the generated reference partitioning pattern is then used 42 to encode the block of texels.

Abstract: In a graphics processing system, when using a graphics texture that is stored in memory as YUV texture data, the YUV texture data is stored in the texture cache from which it is to be read when generating a render output such that the data values for a chrominance data element and its associated set of one or more luminance data elements of the texture are stored together as a group in the cache. The group of data in the cache is tagged with an identifier for the data values of the chrominance data element and its associated set of one or more luminance data elements that is useable to identify the chrominance data element and its associated set of one or more luminance data elements in the cache, and that is indicative of a position in the YUV graphics texture.

Abstract: When sampling a cube map when rendering in a graphics processing system, the vector representation of the desired cube map sample provided by the application is converted into a 2D position on one of the faces of the cube map for use by the texturing unit of the graphics processing pipeline.The determined 2D texture coordinates (S, T) are represented using standard 32-bit IEEE 754 floating point numbers, and the 3-bit face index for the cube map is included in one of the numbers representing the texture coordinates by packing it into the sign bit and the top two bits of the exponent to provide a modified texture coordinate value.The modified 32-bit texture coordinate representation is then provided together with the 32-bit floating point number corresponding to the other texture coordinate as the cube map descriptor to the texturing unit of the graphics processing pipeline.

Abstract: A data processing system is used to evaluate a data processing function by executing a sequence of program instructions including an intermediate value generating instruction Inst0 and an intermediate value consuming instruction Inst1. In dependence upon one or more input operands to the evaluation, an embedded opcode within the intermediate value passed between the intermediate value generating instruction and the intermediate value consuming instruction may be set to have a value indicating that a substitute instruction should be used in place of the intermediate value consuming instruction. The instructions may be floating point instructions, such as a floating point power instruction evaluating the data processing function ab.

Abstract: A programmable execution unit of a graphics processor that executes program instructions to perform graphics shading operations can use at least two different register file mapping configurations for mapping registers to execution threads.When a shader program is to be executed, how the shader program will use the registers is considered and the register file mapping configuration to use for the shader program is then selected based on the assessment of the register use by the shader program.Appropriate state information is then set to cause the threads being executed by the programmable execution unit to use the registers according to the selected register file mapping configuration when executing the shader program.

Abstract: Operating a graphics processing pipeline that includes processing stages including a rasteriser that rasterises input primitives to generate graphics fragments to be processed, each graphics fragment having one or more sampling points associated with it, and a renderer that processes fragments generated by the rasteriser to generate output fragment data for output to a render output, comprising the following steps: (i) determining first information to test whether at least a part of a primitive should be processed further; (ii) using at least some of the first information to decide whether to process at least a part of the primitive further; and if it is decided that at least a part of the primitive is to be processed further: (iii) determining further information to be used in further processing of the primitive; and (iv) further processing at least a part of the primitive using the determined further information.

Abstract: A graphics virtual texturing system in which textures stored in a storage medium of a host system are divided into respective pages that are then loaded into a local memory of a graphics processing system for use. If the texture page that is required for performing a texturing operation at an originally desired level of detail (52) is not present in the local memory of the graphics processing system (53), the virtual texture lookup process loops back to try to sample the texture at an increased level of detail (55), and so on, until texture data that can be used is found in the local memory of the graphics processing system (53). This allows the texturing operation to proceed using texture data for the texel positions in question from a higher level (less detailed) mipmap in place of the originally desired texture data.

Abstract: When an atomic operation is to be executed for a thread group by an execution stage of a data processing system, it is determined whether there is a set of threads for which the atomic operation for the threads accesses the same memory location. If so, the arithmetic operation for the atomic operation is performed for the first thread in the set of threads using an identity value for the arithmetic operation for the atomic operation and the first thread's register value for the atomic operation, and is performed for each other thread in the set of threads using the thread's register value for the atomic operation and the result of the arithmetic operation for the preceding thread in the set of threads, to thereby generate for the final thread in the identified set of threads a combined result of the arithmetic operation for the set of threads.

Abstract: Each block of texture data elements is encoded as a block of texture data that includes: data indicating how to generate a set of data values to be used to generate data values for a set of the texture data elements that the block represents; data indicating a set of integer values to be used to generate the set of data values to be used to generate data values for a set of the texture data elements that the block represents; data indicating a set of index values indicating how to use the generated set of data values to generate data values for texture data elements of the set of texture data elements that the generated set of data values is to be used for; and data indicating the indexing scheme that has been used for the block.
