Abstract: The present disclosure relates to a data processing resource for performing data processing tasks for a host processor, the data processing resource comprising: control circuitry to receive, from the host processor, a request for the data processor unit to perform a processing job; an iterator unit to process the request and generate a workload comprising one or more tasks for the requested processing job; one or more execution units to perform the one or more tasks, wherein the iterator unit is configured to allocate the one or more tasks to the one or more execution units based on control signals from the control circuitry, wherein the control circuitry is further configured to switch an operation mode of at least one execution unit from a normal operation mode to a reduced operation mode by controlling the iterator unit to reduce an amount of task allocated to the at least one execution unit.

Abstract: A data processing system (1) comprises a plurality of processing units (11) and a controller (30) operable to allocate processing units of the plurality of processing units into respective groups of the processing units, wherein each group of processing units comprises a set of one or more of the processing units of the plurality of processing units. The data processing system further comprises an arbiter (31, 32) for each group of processing units for controlling access by virtual machines (33, 34) that require processing operations to the processing units of the group of processing units that the arbiter has been allocated.
