    摘要： A mechanism is provided for constructing an oversampled waveform for a set of incoming signals received by a receiver. In one implementation, the oversampled waveform is constructed by way of cooperation between the receiver and a waveform construction mechanism (WCM). The receiver receives the incoming signals, samples a subset of the incoming signals at a time, stores the subsets of sample values into a set of registers, and subsequently provides the subsets of sample values to the WCM. The WCM in turn sorts through the subsets of sample values, organizes them into proper orders, and “stitches” them together to construct the oversampled waveform for the set of incoming signals. With proper cooperation between the receiver and the WCM, and with proper processing logic on the WCM, it is possible to construct the oversampled waveform for the incoming signals without requiring large amounts of resources on the receiver.

    摘要： This disclosure describes systems and methods for determining a voltage margin (or margin) of a serializer/deserializer (SerDes) receiver in mission mode using a SerDes receiver. This is done by time-division multiplexing a margin determination and a tap weight adaptation onto the same hardware (or software, or combination of hardware and software). In other words, some parts of a SerDes receiver (e.g., an error slicer and an adaptation module) can be used for two different tasks at different times without degrading the effectiveness or bandwidth of the receiver. Hence, the disclosed systems and methods allow a SerDes receiver to determine the SerDes margin in mission mode and without any additional hardware or circuitry on the receiver chip.

    摘要： A system and methods for recovering data from an input data signal are disclosed. The system includes a transmitter for conveying a data signal filtered by a finite impulse response (FIR) filter to a receiver via a channel. The receiver uses an adaptive algorithm to determine update signals for a pre-cursor tap coefficient of the FIR based on samples taken from the received data signal and conveys the update signals to the FIR. To generate update signals, the receiver samples the data signal at a phase estimated to correspond to a peak amplitude of a pulse response of the channel. The phase is based on a clock recovered from the data signal. The update signals increase or decrease a pre-cursor tap coefficient setting in response to determining that the phase corresponds to a point earlier or later, respectively, than the peak amplitude of the channel's pulse response.
