Abstract:
1. Data processing apparatus comprising: a data processing module, which can be operated in a first operating mode with a first power consumption and a second operating mode, wherein a second power consumption of the data processing module in the second operating mode is smaller than the first power consumption or is equal to zero; a signaler for signaling a possibility that the data processing module can be placed from the first operating mode to the second operating mode; a provider for providing a time-varying control signal; and a placer for placing the data processing module from the first operating mode to the second operating mode, wherein the placer is formed to place the data processing module into the second operating mode, only when the signaler signals the possibility and the control signal fulfils a predetermined condition; a further data processing module, which can be operated in a first operating mode with normal power consumption and in a second operating mode, wherein a power consumption of the further data processing module in the second operating mode is smaller than the normal power consumption or equal to zero; a further signaler for signaling a possibility that the further data processing module can be placed from the first operating mode into the second operating mode; and a further placer for placing the further data processing module into the second operating mode, when the further signaler signals the possibility and the control signal fulfils a predetermined condition.
