Abstract
A method of operating a chipset for saving power consumption is provided. Basic operating units, control units and input/output ports are used to simulate the operation inside the chipset. Any idling operating units are temporarily shut down, only to be activated again on demand. Ultimately, less power consumption is used and less heat is generated by the chipset.
Claims10
A method of operating a chipset for saving power consumption, wherein said chipset includes a plurality of basic operating units, a plurality of control units and a plurality of input/output ports, and each operating units and input/output port is at least connected to a control unit, comprising said steps of:
- when said chipset no longer requires a particular operating unit, wherein said chipset activates said control unit of said operation unit to disable said operating unit so that said operating unit switches to an power-saving mode;
- and
- when said chipset requires a particular operating unit, wherein said chipset activates said control unit of said operating unit to enable said operating unit so that said operating unit switches to an active mode for performing some computations.
A method of operating a chipset for saving power consumption, wherein said chipset includes a plurality of basic operating units, a plurality of control units and a plurality of input/output ports, and each operating units and input/output port is at least connected to a control unit, comprising said steps of:
- when said chipset no longer requires said operation of a particular operating unit, wherein said chipset sends a request signal to said control unit of said operating unit so that said control unit can disable said operating unit and switch said operating unit into an power-saving mode;
- and
- when said chipset requires said operation of a particular operating unit, wherein said chipset sends a request signal to said control unit of said operating unit so that said control unit can enable said operating unit and switch said operating unit into an active mode.
