<p>A data processing device has a processor (10) operable at selectable ones of a plurality of performance levels. The processor generates a workload data vector indicating a workload of the processor as a function of time. A memory stores a set of reference workload vectors. A pattern matcher (18) detects whether there is a matching reference workload data vector. A performance level controller (19) selects the performance level of the processor based on control information that is stored in combination with the matching workload data vector.</p> |
