Abstract
A method for modifying the frequency of a clock signal clocking an integrated circuit supplied by a voltage controller, comprises, in response to a command for the modification, varying the frequency of the clock signal at a rate allowing a supply voltage to be controlled by the controller. The variation comprises at least one series of successive divisions of the frequency of the clock signal into successive intermediate signals of respective intermediate frequencies.
Claims14
A method comprising:
- controlling, by a supply voltage controller of an integrated circuit, a supply voltage provided to the integrated circuit;
- providing, by a clock signal generator of the integrated circuit, a clock signal to the integrated circuit;
- receiving, by the clock signal generator, a command to modify a frequency of the clock signal;
- and
- in response to the command, varying, by a frequency divider, the frequency of the clock signal with at least one series of successive divisions of the frequency of the clock signal into successive intermediate signals of respective intermediate frequencies, each division of the at least one series being limited so as to limit a load variation presented by the integrated circuit to the supply voltage-controlled by the controller.

An integrated circuit comprising:
- a supply voltage controller configured to control a supply voltage provided to the integrated circuit;
- a clock signal generator configured to provide a clock signal to the integrated circuit, and receive a command to modify a frequency of the clock signal;
- and
- a frequency divider configured to, in response to the command, vary the frequency of the clock signal with at least one series of successive divisions of the frequency of the clock signal into successive intermediate signals of respective intermediate frequencies, wherein each division of the at least one series is configured to be limited so as to limit a load variation presented by the integrated circuit to the supply voltage controlled by the controller.
