METHOD AND DEVICE FOR ELECTRIC SUPPLY IN A DIGITAL PROCESSOR OF MOBILE APPARATUS, AS WELL AS MOBILE APPARATUS WITH DIGITAL PROCESSOR

摘要

The present invention relates to a method for supplying electrical power to a digital processor of a mobile device, comprising measuring the supply voltage of the processor, comparing the supply voltage with a reference value, and controlling the control circuit providing the supply voltage according to the difference between the pediga supply voltage and the reference value. It is characterized in that the expected time (T) of the increase in electrical energy demand is determined, and the control circuit mode is modified in advance at a prescribed time (T '). The invention further relates to a mobile device with a digital processor and a controlled power supply for the digital processor, which is determined by a supply voltage reference value produced by the controlled power supply. It is characterized by a microprocessor for determining the time (T) of the increase in processor power consumption and a means for pre-modifying the mode of operation of the control circuit at a predetermined time (T ').
