Abstract: A warp processing unit controls, in dependence on a warp program counter shared between a plurality of threads processing respective graphics fragments, fetching of a next instruction to be executed for at least some of the plurality of threads. In response to a determination that a given subset of threads is to be discarded when at least one other subset of threads is to continue, the warp processing unit processes the given subset of threads in a discarded state. For a thread processed in the discarded state, execution of instructions continues for the discarded thread, and at least one of: generation of data access messages triggered by the discarded thread is suppressed; and at least one processing operation, which would be deferred until completion of the discarded thread had the thread not been discarded, is enabled to be commenced independently of an outcome of the discarded thread.

Abstract: A method and an apparatus for generating a signature representative of the content of a region of an array of data in a data processing system, where the region of the array of data comprising plural data positions, and each data position having an associated data value or values. A data value or values for a data position of the region of the data array is/are generated. The data value or values for the data position of the region of the data array is/are written to storage that stores the region of the data array as it is being generated. A signature representative of the content of the region of the data array is generated in parallel with the data value or values for the data position of the region of the data array being written to the storage.

Abstract: A graphics processing apparatus comprises fragment generating circuitry to generate graphics fragments corresponding to graphics primitives, thread processing circuitry to perform threads of processing corresponding to the fragments, and forward kill circuitry to trigger a forward kill operation to prevent further processing of a target thread of processing corresponding to an earlier graphics fragment when the forward kill operation is enabled for the target thread and the earlier graphics fragment is determined to be obscured by one or more later graphics fragments. The thread processing circuitry supports enabling of the forward kill operation for a thread including at least one forward kill blocking instruction having a property indicative that the forward kill operation should be disabled for the given thread, when the thread processing circuitry has not yet reached a portion of the thread including the at least one forward kill blocking instruction.
