Abstract: When rendering a scene that includes a complex object made up of many individual primitives, rather than processing each primitive making up the object in turn, a bounding volume which surrounds the complex object is generated and the scene is then processed using the bounding volume in place of the actual primitives making up the complex object. If it is determined that the bounding volume representation of the object will be completely occluded in the scene (e.g. by a foreground object), then the individual primitives making up the complex object are not processed. This can save significantly on processing time and resources for the scene.

Abstract translation: 当渲染包括由许多单独的基元组成的复杂对象的场景时，而不是依次对每个组成对象的每个基元进行处理，生成围绕复杂对象的边界体积，然后使用边界体积来处理场景 构成复杂对象的实际原语。 如果确定对象的边界体积表示将被完全遮蔽在场景中（例如，通过前景对象），则构成复杂对象的各个基元不被处理。 这可以显着节省场景的处理时间和资源。

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 data processing apparatus and method are provided for processing a received workload in order to generate result data. A thread group generator generates from the received workload a plurality of thread groups to be executed to process the received workload. Each thread group consists of a plurality of threads, and at least one thread group has an inter-thread dependency existing between the plurality of threads. Each thread may be either an active thread whose output is required to form the result data, or a dummy thread required to resolve the inter-thread dependency for one of the active threads but whose output is not required to form the result data. The thread group generator identifies for each thread group any dummy thread within that thread group. A thread execution unit then executes each thread within a thread group received from the thread group generator by executing a predetermined program comprising a plurality of program instructions. Execution flow modification circuitry is responsive to the received thread group having at least one dummy thread, to cause the thread execution unit to selectively omit at least part of the execution of at least one of the plurality of instructions when executing each dummy thread, in dependence on control information associated with the predetermined program. In one particular embodiment the received workload is a graphics rendering workload and the thread execution unit performs graphics rendering operations in order to generate as the result data pixel values and associated control values. Such an approach can yield significant improvements in performance, as well as reducing power consumption.

Abstract: A graphics processing unit 2 includes a texture pipeline 6 which performs filter operations upon texture values. If the texture values are integer texture values, then they may be processed by the texture pipeline in a variable order corresponding to the order in which they are retrieved from a memory 4. If the texture values are floating point texture values, then they are processed in a fixed order in order to ensure result invariants as the filter operation is non-associative for floating point values. The filter operation is not commenced until all of the floating point texture values have been retrieved from the memory 4 and other available for processing.

Abstract: Apparatus for processing data includes processing circuitry 16, 18, 20, 22, 24, 26 and decoder circuitry 14 for decoding program instructions. The program instructions decoded include a floating point pre-conversion instruction which performs round-to-nearest ties to even rounding upon the mantissa field of an input floating number to generate an output floating point number with the same mantissa length but with the mantissa rounded to a position corresponding to a shorter mantissa field. The output mantissa field includes a suffix of zero values concatenated the rounded value. The decoder for circuitry 14 is also responsive to an integer pre-conversion instruction to quantise and input integer value using round-to-nearest ties to even rounding to form an output integer operand with a number of significant bits matched to the mantissa size of a floating point number to which the integer is later to be converted using an integer-to-floating point conversion instruction.

Abstract: A tile-based graphics processor includes tile processing circuitry that has both a tile buffer and a per-pixel general purpose data store. The per-pixel general purpose data store is read accessible and write accessible by the tile processing circuitry to store intermediate values. These intermediate values are generated by the tile processing circuitry and then consumed by the tile processing circuitry to generate the output values for the tile being processed.
