  • Adjustment of power-saving strategy depending on working state of CPU
    Patent number: 8281171
    Abstract: In a method for adjusting power-saving strategy of a peripheral device controller in communication with a CPU, whether the CPU is in a working state while the peripheral device enters a power-saving mode is first determined. Then, interrupt the CPU at relatively short intervals during the power-saving mode if the CPU is in the working state; and interrupt the CPU at relatively long intervals during the power-saving mode if the CPU is not in the working state.
    Type: Grant

  • USB controller with intelligent transmission mode switching function and the operating method thereof
    Patent number: 7185132
    Abstract: There is provided a USB controller with an intelligent transmission mode switching function and the operating method thereof. The USB controller includes a host controller, a device controller, a data line set, and a monitor unit, wherein the data line set includes a D+ data line and a D? data line which are manipulated by the monitor unit to selectively couple to the host controller and a device controller. By way of the switching manipulation provided by the monitor unit, the transmission mode of the USB controller can be periodically switched between the host mode and the device mode, so that the transmission mode of the USB controller can be detected and settled readily in order to conduct data communication with other devices.
