A register renaming table recovery method for use in a processor includes the following steps. Firstly, a flushing operation is performed on a renaming-history table according to a flushed ID. Then, a first renamed ID corresponding to a first register is acquired from an unflushed row of the renaming-history table that is immediately adjacent to the flushed ID. If the first renamed ID is occupied, a register renaming table is updated to rename the first register according to the first renamed ID. Whereas, if the first renamed ID is not occupied, the register renaming table is updated to keep the first register unrenamed.

Register renaming table recovery method and system for use in a processor

An automatic configuration system for automatically configuring a connecting interface of a node device in a network is provided. The connecting interface of the node device includes a first pair of connectors and a second pair of connectors. The automatic configuration system includes a switching unit, a first analog circuit unit, a second analog circuit unit and a detecting unit. The detecting unit is used to detect whether a first computed result or a second computed result outputted from the first analog circuit unit or the second analog circuit unit involves signals transmitted from another node device in the network, and accordingly generate a detected result to allow the switching unit to execute a switching operation and selectively connect the transmitting unit to the first or second pair of connectors, so as to ensure that data can be transmitted or received reliably in the network.

A receiver with baseline wander compensation is applicable to a digital communication system. The receiver includes an Analog-to-Digital Converter (ADC), a slicer, a threshold value detector, a gain controller, a baseline wander compensator, a delay circuit, an analog gain stage, and a digital gain stage. The baseline wander compensator is used to perform an operation and a filtering process on a voltage obtained prior to processing by the slicer and a voltage after the processing so as to obtain a baseline wander voltage value for compensation and control. The threshold value detector and the gain controller dynamically produce control signals of analog gain and digital gain. The analog gain stage compensates degrading of communication signals passing through transmission channels in an analog gain manner. The delay circuit is used to compensate the delay of the conversion performed by the ADC. The digital gain stage compensates insufficiency of the analog gain.

Receiver with baseline wander compensation

A data transmission device is applied to a network apparatus having an automatic crossover function, and is connected to a transmission control unit, such that the transmission control unit detects an operating status of the network apparatus and accordingly generates a control command. Thereby, a current source generating unit provides current sources to a first-mode converting unit and a second-mode converting unit according to the control command. This allows a suitable data transmission processing mode to be selected automatically and instantaneously for the operating status of the network apparatus by the current sources from the current source generating unit and the control command generated from the transmission control unit, so as to achieve power saving, low distortion and/or anti-interference.

Data transmission device

An active hybrid circuit for a full duplex channel generates a duplicated voltage at the current output stage to reduce the energy of the transmitter transmitted to the receiver. The active hybrid circuit cancels the energy of the transmitter transmitted to the receiver when it is operated in a full duplex channel with high-speed transmission. The active hybrid circuit for full a duplex channel comprises a transmit digital-to-analog converter for generating an analog transmit signal, a receive analog-to-digital converter for receiving an analog receive signal, a duplicated voltage digital-to-analog converter for generating a corresponding duplicated voltage according to the analog transmit signal of the transmit digital-to-analog converter, and a plurality of signal combiners for subtracting the duplicated voltage from the analog transmit signal to cancel the influence of analog transmit signal to the analog receive signal.
