ABSTRACT:
The invention provides a voltage-controlled device, method and computer device capable of dynamically regulating voltage and effectively saving energy. The voltage-controlled device receives a VID from a CPU, determines a core voltage according to a load line defined therein, and supplies the core voltage to the CPU. The voltage-controlled device has a load line register set and a write logic. The load line register set has a plurality of registers, and the values of which represent the defined load line. The write logic changes the values of the registers in the load line register set according to a write signal.
