METHOD AND DEVICE FOR CONTROLLING POWER-ON OF A PROCESSING CIRCUIT

摘要

The present invention relates to a method for controlling the activation of a circuit (PRCU) clocked by a clock signal (CLK), the method comprising a phase of activating the circuit comprising simultaneous steps of increasing a supply voltage (Vs) of the circuit until a nominal supply voltage is reached, and of increasing a frequency of the clock signal until a nominal frequency is reached, the circuit being configured for operating within a certain range of supply voltage values and a certain range of clock signal frequencies below the nominal supply voltage and the nominal frequency.
