Classification: CPC G  H | IPC G

Claim 4:
5. A powering method, applicable to an electronic device comprising a first functional unit, and the powering method comprises:
generating a first clock according to a first clock enable signal;
enabling the first functional unit in response to a signal edge of the first clock, wherein said enabling the first functional unit in response to the signal edge of the first clock comprises:
detecting the signal edge of the first clock;
by using a first operation interface, generating a first power supply signal triggered by the signal edge of the first clock and translating a first operation instruction into a first operation signal, said generating the first power supply signal triggered by the signal edge of the first clock and translating a first operation instruction into a first operation signal comprising detecting the signal edge of the first clock to generate the first power supply signal by using an edge detector, wherein after being completely enabled, the first functional unit outputs a first ready signal; and

enabling the first functional unit according to the first power supply signal; and
operating the first functional unit according to the first operation signal.
