The transmission power control negotiation method includes the first transceiver transmitting first adjustment signal to the second transceiver with a first transmission power; the second transceiver analyzing the first adjustment signal and sending negotiation messages for the first transceiver to adjust the first transmission power; and the first transceiver transmitting following signals with the first transmission power.

Abstract: A method of transmitting a packet via heterogeneous networks, for a transmitter and a receiver using the heterogeneous networks comprising a first network and a second network is disclosed. The method comprises the transmitter transmitting the packet to the receiver via the first network and the second network, to improve robustness of the transmission of the packet; and the transmitter stopping transmitting the packet via the second network after the packet is transmitted successfully via the first network, or stopping transmitting the packet via the first network after the packet is transmitted successfully via the second network; wherein the first network and the second network are of different types or with different characteristics.

Abstract: An apparatus for power management in a network communication system including a legacy first network device is disclosed. The apparatus includes a second network device to serve as a client device to the first network device, a detector to generate a first signal if an idle status occurs in a first traffic from the first network device, and generate a second signal if a second traffic posterior to the first traffic is to be transmitted from the first network device, an identifier in response to the first signal to generate a third signal if the idle status exceeds a predetermined period of time, and a controller to disable the second network device in response to the third signal and hold the first network device from transmitting the second traffic in response to the second signal.

Abstract: A processor and an early-load method thereof are provided. In the early-load method, an instruction is fetched and determined in an instruction fetch stage to obtain a determination result. Whether to early-load an early-loaded data corresponding to the instruction is determined according to the determination result. A target data is fetched according to the instruction in an instruction execution stage if the early-loaded data is not loaded correctly. The early-loaded data is served as the target data if the early-loaded data is loaded correctly.

Abstract: Magic Packet technique is developed to remotely awake a computer host in a sleeping mode on a node through computer network. Instead of utilizing a large amount of memory or a complex algorithm, an algorithm and system, which only utilize two sets of counters and control logics to perfectly detect the Magic Packet according to the characteristics of magic packet are disclosed. According to the present invention, if a LAN controller on a node of the network is in magic packet mode, it will detect all input frames addressed in the node to search a specific data sequence indicative of the Magic Packet frame. Once the controller detects the data sequence, it will notice the power management circuitry of the computer host on the sleeping node to awake the system.

Abstract: In a method and apparatus for detecting a wake packet among data bytes in a packet frame issued by a network device, the data bytes in the packet frame are initially compared with a sync byte to detect start of a synchronization stream of the wake packet. The number of consecutive sync matches of the data bytes in the packet frame with the sync byte is counted, and a partial match flag is set upon detection that the number of consecutive sync matches has reached a predetermined number of sync duplications of the sync byte to indicate that the synchronization stream has been detected in the packet frame. When the partial match flag is set, the data bytes that follow the synchronization stream in the packet frame are compared with address bytes of a destination address assigned to a sleeping node.
