    摘要： The present invention provides a network interface card configuration method and a resource management center, relates to the field of multi-core processors, and resolves a problem in the prior art that a multi-core processor system based on many-core decoupling cannot implement cross-network interface card and cross-network segment data processing. The method includes: obtaining, by the resource management center, a network interface card allocation request of an operating system that runs in a first CPU core, and selecting, from M physical network interface cards and based on a network parameter of a network service required by the operating system, a target physical network interface card that conforms to the network parameter, and selecting at least one target hardware queue from each target physical network interface card; then sending, by the resource management center, a command message to a network interface card controller, and receiving queue information that is of the target hardware queue and fed back by the network interface card controller; and finally, sending, by the resource management center, an instruction message to a CPU controller on a CPU board. The present invention is used to construct a virtual network interface card.

    摘要： A serial protocol interface in a communication device (MD) exchanging data (MOSI, MISO) over a communication link (121, 122, 123) is operated by: - sending output data (MOSI) on (122) the communication link, and - receiving input data (MISO) on (121) the communication link, these input data (MISO) being synchronous with a clock signal (SCK, SCLK) generated at the communication device (MD) and propagated (123) over the communication link (121, 122, 123), - initializing operation by exchanging data over the communication link (121, 122, 123) by sending output data (MOSI) on the communication link (122) at a first data rate, - detecting a signal transition in the input data (MISO) received on the communication link (121), and - once such a transition is detected, exchanging data over the communication link (121, 122, 123) at a second data rate, higher than the first data, with the exchanging of data at a second data rate synchronized (18) as a function of said signal transition.

    摘要： A hot plug method, a host controller, a host, and a PCIe bridge device are provided, and relate to the field of computer technologies, so as to implement remote PCIe device hot plug. The method includes: generating, by a host controller, a first notification packet, where the first notification packet carries hot plug interruption information (s101), and the hot plug interruption information indicates that a first PCIe device is to be hot-plugged; sending, by the host controller, the first notification packet to a host (s102), so that the host performs, according to the first notification packet, a hot plug operation corresponding to the first PCIe device; and receiving, by the host controller, a second notification packet sent by the host, and sending the second notification packet to the user equipment controller (s105), so that the user equipment controller instructs a user to insert or remove the first PCIe device, where the second notification packet is used to indicate that the hot plug operation corresponding to the first PCIe device is completed.

    摘要： In one example in accordance with the present disclosure, a computing system is provided. The computing system includes a first bus controller to control X bus lanes, a second bus controller to control Y bus lanes, a 2-to-1 X lane multiplexer, and a Y lane system component, where Y>X>0. X lanes from the first bus controller are coupled to the 2-to-1 X lane multiplexer. X lanes from the second bus controller are coupled to the 2-to-1 X lane multiplexer, and Y-X lanes from the second bus controller are coupled directly to the Y lane system component. In addition, X lanes from the 2-to-1 X lane multiplexer are coupled to the Y lane system component.
