Abstract
A method for centralized link power management control (CLMC), performed by a north-bridge of a processing unit, comprises the following steps. A data transmission status of a bus is monitored. CLMC is activated to configure devices corresponding to the bus in order to speed up data transmission of the bus when detecting that the data transmission status of the bus is continually busy. CLMC is activated to configure devices corresponding to the bus in order to slow down data transmission of the bus when detecting that the data transmission status of the bus is continually idle.
Claims20
A method for centralized link power management control, performed by a control unit of a north-bridge, comprising:
- monitoring a data transmission status of a bus;
- when it is detected that the data transmission status of the bus is continually busy, initiating centralized link management control to configure a device corresponding to the bus for speeding up data transmission of the bus;
- when it is detected that the data transmission status of the bus is continually idle, initiating centralized link management control to configure the device corresponding to the bus for slowing down data transmission of the bus.
A system for centralized link power management control, comprising:
- a processor;
- and
- a north-bridge, coupled to the processor through a bus, comprising:
- a control unit, monitoring a data transmission status of the bus, when it is detected that the data transmission status of the bus is continually busy, initiating centralized link management control to configure a device corresponding to the bus for speeding up data transmission of the bus, when it is detected that the data transmission status of the bus is continually idle, initiating centralized link management control to configure a device corresponding to the bus for slowing down data transmission of the bus.
