A data processing system comprises a plurality of sub-circuits, a clock generator provided with a control circuit, a pool of oscillator circuits comprising at least three oscillator circuits, and a multiplexing circuit coupled between the pool and clock inputs of the sub-circuits. The multiplexing circuit has a control input coupled to a control output of the control circuit. The multiplexing circuit is configured to couple any selectable one of the oscillator circuits in the pool to a clock input of each of the sub-circuits. The control circuit is configured to set the frequencies of respective ones of the clock circuit by controlling the multiplexing circuit to supply clock signals derived from selected ones of the oscillator circuits to the sub-circuits.

Clock generator

A data-processing system is described comprising: &#x2022; A plurality of data-processing devices () &#x2022; A data-handling facility () shared by the data-processing devices, &#x2022; An aggregation facility () for receiving signals (R, R, R, R) indicative for individual requirements from the data-processing devices for a performance of the shared data-handling facility and for providing a control signal (RA) indicative for a required activity level to meet the aggregated requirements, &#x2022; a control device () for controlling an activity level of the data-handling facility depending on the control signal (RA). Additionally a data-processing method is described.
