Abstract:
An electronic circuit includes processors (CPU1, CPU2) operable to make respective voltage requests (Vcpu1, Vcpu2), and a power management circuit (1470) having a controllable supply voltage output (VDD1) is coupled to said processors (CPU1, CPU2) and further has a voting circuit (4520) responsive to the voltage requests (Vcpu1, Vcpu2) and operable to automatically establish a function (Fct) of the respective voltage requests (Vcpu1, Vcpu2) to control the controllable supply voltage output (VDD1).
