摘要： A method and apparatus for testing a data transfer system. The method comprises the steps of storing a first table, the first table noting at least a time of issuance of at least one command and a time of completion of the command and comparing the time of issuance of the command and the time of completion of the command. A timeout condition is registered if the processor determines that a time longer than a predetermined time elapsed between the time of issuance of the command and the time of completion of the command.

摘要： A waveform processing system may include a compensation circuit to adjust a voltage supplied to an output stage, wherein a supplied voltage is controlled to substantially maintain constant power dissipation in the output stage, and wherein the compensation circuit is configurable independently from the amplification stage. In an illustrative embodiment, a control circuit may be independently configurable with respect to an amplifier that generates a signal for the output stage, and the control circuit may bias a compensation circuit that provides thermal tail compensation for an output stage transistor. In some embodiments, the bias may operate the compensation circuit (i) to maintain a substantially constant power condition in the output stage transistor to substantially reduce thermal tail effects, and (ii) to maintain the output stage transistor in an unsaturated operating condition.

摘要： Methods for processing waveforms may include decimating an over-sampled waveform by identifying samples for which the sample's position within a data period indicates that is closest to a selected time within a data period. In some example applications, the selected time may be determined as a preferred time to sample the waveform within a data period. In an illustrative example, a sequence of samples representing an over-sampled waveform may be reduced by identifying a sample in each data period that is closest in time to the selected time. In another illustrative example, a sample within each data period may be identified if it falls within a range that is a function of the selected time within the data period and an integral ratio of a sample period to the data period. The identified samples may be used to reconstruct the original waveform with fewer samples than the over-sampled waveform.

摘要： Methods for processing waveforms may include using temporal descriptor information about an input waveform to selectively request a segment of the input waveform that, when processed by a filter, produces a segment of an output waveform. In an illustrative example, waveform descriptor information may be used to request data to perform unary or filtering operations, or to perform one or more processes that involve at least one additional waveform. In combination with a filter descriptor that identifies, for example, upsampling factor, delay samples, and startup samples, complex waveform operations may be processed by selectively pulling input waveform segment data to generate a segment of the output waveform. In embodiments that process sequential waveform segments, filter tap states may be initialized using state information from processing of a previous waveform segment.
