Abstract
The invention concerns a circuit comprising: a voltage generator adapted to generate a variable supply voltage for powering a processing core; a frequency generator adapted to generate a variable frequency clock signal of the processing core and comprising a frequency locked loop having: a digitally controlled oscillator configured to generate the variable frequency clock signal; and a controller () configured to generate a digital control signal (C_FREQ), wherein the controller is configured to implement a frequency transition of the variable frequency clock signal from a first frequency to a second lower frequency by generating: a first value of the digital control signal (C_FREQ) to apply a first reduction in the frequency of the variable frequency clock signal to a third frequency lower than the second frequency; and further values of the digital control signal (C_FREQ).
