Delegating data processing tasks

Abstract

Apparatuses, methods, systems, chip-containing products and computer-readable storage media are disclosed. Data processing circuitry performs first data processing operations and second data processing operations. The first data processing operations comprise a first delegation action that signals a first delegated task to be performed by the second data processing operations. Performance of the first delegated task by the second data processing operations comprises a second delegation action, that causes extension processing circuitry to perform a second delegated task asynchronously to the second data processing operations performed by the data processing circuitry. Completion of the first delegated task by the second data processing operations is signalled to the first data processing operations providing a data item with an associated indicator set. The set indicator causes the first data processing operations, when a delegated-task-related data processing operation that depends on the data item is to be performed, to clear the indicator and to perform a synchronization of the data processing circuitry with a result of the second delegated task before performing the delegated-task-related data processing operation.
