A data input buffer in a semiconductor is capable of avoiding operation speed deterioration of the data input buffer due to the temperature condition or process characteristic. The data input buffer in a semiconductor device includes an input detecting unit for detecting logic level of input data by comparing the voltage level of the input data with a reference voltage, a current driving capability adjusting unit for adjusting current driving capability of the input detecting unit based on at least one of temperature condition and process characteristic, and a buffering unit for buffering the output signal from the input detecting unit.

An approach is provided for managing an allocation of a bandwidth of a dedicated channel in a network being utilized by an application performing a replication of data from a first to a second storage resource. Checks of parameters specified by the application are determined. The parameters include, but are not limited to, average compression ratio, compression ratio trend, throughput, throughput trend, and round trip time. Respective high and low threshold values for the parameters are determined. At least one of the checks of the parameters is executed, which determines a violation of a threshold value for one of the parameters. If the violation of the high threshold value is determined, an increase in the bandwidth is triggered. If the violation of the low threshold value is determined, a decrease in the bandwidth is triggered.

A network apparatus coupled to a plurality of nodes. The nodes are clustered into a plurality of groups. The network apparatus includes a storage component and a controller. The storage component is configured to store a plurality of group numbers corresponding to the groups and a plurality of node numbers corresponding to the nodes. The controller is configured to transmit a broadcast packet to all of the nodes. The broadcast packet includes a local network broadcast message. The local network broadcast message includes operating information. The local network broadcast message corresponds to at least one of the group numbers and the node numbers. Each of the nodes determines whether to dismiss the operating information of the broadcast packet according to the local network broadcast message of the broadcast packet.

In a work machine, a control unit controls a pilot control valve for controlling the opening area of a first direction switch valve in executing the combined operation to be less than or equal to that in executing a single operation. The combined operation represents an operation of simultaneously operating first and second actuators. The single operation represents an operation of operating only the first actuator. Further, the control unit determines the opening area of the first direction switch valve in the combined operation based on a hydraulic pressure detected by a hydraulic pressure detector unit.

Embodiments of the present invention disclose a data synchronization method, device, electronic device and storage medium, which relate to the technical field of data management and can improve data synchronization efficiency. The method includes: selecting at least one first node from the first node group; no data to be sent on the nodes in the first node group; acquiring a node carrying the first mark in the second node group; The nodes in the two-node group have data to be sent, the mark is used to identify the number of nodes in the node group that are providing services, and the value of the first mark is less than the preset mark threshold; One of the nodes is selected as the second node, so that the first node pulls data from the second node. The invention is suitable for managing and maintaining data or nodes in a cluster of node equipment such as computers.

A semiconductor memory device is capable of transferring address signals at high speed and improving the operation reliability even though an input rate of an address signal increases, and thus a degradation of an operation speed caused by applying a bus inversion scheme can be prevented and power consumption can be reduced. The semiconductor memory device includes a bus inversion decoding block configured to determine whether a plurality of address signals are inverted or not by decoding an indication control signal, and an address buffer block configured to receive two address signals per one cycle of an external clock, align the received address signals for parallel processing, and transfer the address signals or inverted address signals according to an output of the bus inversion decoding block.

A laser-based uplink and downlink visible light communication link device belongs to the field of visible light communication. The data of the Ethernet physical layer is directly extracted through the interface processing hardware circuit, and there is no need to establish the communication network interface between Ethernet and FPGA or DSP, which simplifies the complexity of system integration and reduces the development cycle, and avoids the problem of reducing the rate of visible light communication; The interface processing circuit and the differential-to-single-ended and single-ended-to-differential circuits are integrated into one module to avoid the problems of high-speed signal attenuation and signal reflection during transmission.
