Abstract: A wireless communication method and device are provided. The wireless communication method includes the steps of using a transmitter to notify the receiver that a lane number, which is the number of active lanes, will be changed when the lane number will be changed; using the transmitter to transmit one control symbol to the receiver when the current data has been transmitted to the receiver; and using the transmitter to transmit new data to the receiver through the changed active lanes.

Abstract: The disclosure provides an electronic device having network auto-switching functions and a network auto-switching method utilized in an electronic device. The electronic device comprises: a first network connecting unit having a first network transmission specification; and a second network connecting unit having a second network transmission specification different from the first network transmission specification. The network auto-switching method comprises: utilizing a detecting unit for detecting network connecting statuses of the first network connecting unit and the second network connecting unit to generate a detecting result; utilizing a network access unit for determining to select the first network connecting unit or the second network connecting unit to perform a network connecting operation or to not perform the network connecting operation at least according to the detecting result.

Abstract: A network notifying device applied to a first network device is provided, where the first network device is coupled to a second network device, and the network notifying device includes an interface control circuit, a clock generator and a counter. The interface control circuit is coupled to the second network device, and stores a notify command. The clock generator is utilized for generating a clock signal. The counter is coupled to the interface control circuit and the clock generator, and the counter counts the clock signal to periodically generate a trigger signal to the interface control circuit to trigger the interface control circuit to transmit the notify signal to the second network device. In addition, operations of the clock generator and the counter are independent from a processor of the first network device.

Abstract: A state machine with a dynamic clock gating function according to the invention is disclosed. In the state machine, a gating clock control logic is used to gate a clock signal input to flip-flops which do not need a clock sample input. Accordingly, the total capacitance of capacitors which are charged/discharged following the state transition of a clock signal is greatly reduced, thereby decreasing the power consumption of the state machine.
