Abstract: This application provides a wireless charging circuit and system, an electronic device, and a control method, and relates to the field of wireless charging technologies, to alleviate a problem of small charging power of an electronic device having a wireless reverse charging function. In the wireless charging circuit, a first voltage conversion circuit converts a supply voltage into a first battery voltage of a first battery, to charge the first battery. The first voltage conversion circuit further outputs the first battery voltage provided by the first battery. A second voltage conversion circuit boosts the first battery voltage. The second voltage conversion circuit includes a first boost circuit and at least one stage of switched-capacitor direct current converter that are connected in series. A first alternating current/direct current conversion circuit converts a direct current voltage output by the second voltage conversion circuit into an alternating current voltage.

Abstract: A data forwarding chip and a server are disclosed. The server includes a data forwarding chip, a network interface card, and a processor. The data forwarding chip is separately connected to the network interface card and the processor through a bus. After receiving a data forwarding request sent by the processor or the network interface card, the data forwarding chip forwards, based on a destination address of the data forwarding request through an endpoint port that is on the forwarding chip and that is directly connected to a memory space corresponding to the destination address of the data forwarding request, to-be-forwarded data specified in the data forwarding request, such that when the server sends or receives data, cross-chip transmission of data between processors occurs, thereby reducing a data transmission delay.

Abstract: In a data processing method, a timeout aggregation node of a cluster obtains first data that is partial aggregated data in a data-intensive computing task. The first data carries a first identifier of a timeout node indicating that a timeout occurs on the timeout node. The timeout aggregation node obtains second data of the timeout node based on the first identifier, where the second data is to-be-aggregated data sent by the timeout node. The timeout aggregation node aggregates the first data and the second data according to a preset rule to obtain third data that is complete aggregated data. The timeout aggregation node then notifies each computing node in the cluster of the third data.
