Abstract:
1. Apparatus for processing data, said apparatus comprising: a processor operable to perform data processing operations, said processor being operable to generate a performance control signal indicative of a desired data processing performance level of said processor; and one or more further circuits responsive to said performance control signal to operate so as to support said desired data processing performance level of said processor; wherein at least while responding to a change in said performance control signal, said one or more further circuits are operable to generate a current operation signal indicative of current operation of said one or more further circuits, wherein said one or more further circuits include a voltage controller operable to generate a power signal for said processor at a plurality of different voltage levels, said current operation signal being indicative of a maximum power supply voltage that can currently be supported by said voltage controller.
