摘要： A pipelined decision feedback unit (DFU) is disclosed for use in reduced-state Viterbi detectors with local feedback. The disclosed pipelined decision feedback unit improves the maximum data rate that may be achieved by the reduced state Viterbi detector by the pipelined computation of partial intersymbol interference-based estimates. A pipelined decision feedback unit is thus disclosed that computes a plurality of partial intersymbol interference based estimates, wherein at least one partial intersymbol interference-based estimate is based on a selected partial intersymbol interference-based estimate; and selects the selected partial intersymbol interference-based estimate from among partial intersymbol interference-based estimates for path extensions into a state.

摘要： A network processor for determining one or more network operations to be performed on a packet of data in a network comprises processing circuitry and protocol indicator circuitry. The packet of data contains information populating a plurality of protocol header fields. Moreover, the protocol indicator circuitry comprises a plurality of memory elements, each memory element associated with a protocol header field in the plurality of protocol header fields. The processing circuitry determines the one or more network operations to be performed on the packet of data at least in part by addressing one or more lookup tables with the contents of a subset of the plurality of protocol header fields in the packet. This subset is determined by reference to the memory elements in the protocol indicator circuitry. Each memory element is capable of being programmed to indicate whether the associated protocol header field is to be utilized by the processing circuitry in addressing the one or more lookup tables.

摘要： Various systems and methods for controlling DC motors are disclosed herein. For example, one method provides for controlling a polyphase, brushless DC motor. The method includes providing a DC motor that has a plurality of phases. Such a DC motor operates by inducing a current in the plurality of phases in accordance with a plurality of commutation states. In the example, six commutation states are discussed, but fewer than or more than six commutation states may exist. The method further includes initializing a count, inducing a current in the plurality of phases in accordance with a first commutation state, and incrementing the count until the current achieves a threshold in the first commutation state. Then, a current is induced in the plurality of phases in accordance with a second commutation state, and the count is decremented until the current achieves the threshold in the second commutation state. The sign bit of the count is stored, and a desired initial commutation state is determined based at least in part on the sign bit of the count.

摘要： Roughly described, a packet switching fabric contains a separate queue scheduler for each combination of an input module and a fabric output port. The schedulers may also be specific to a single class of service. Each queue scheduler schedules its packets without regard to state of other input queues and without regard to packets destined for other output ports. In an aspect, the fabric manages per-flow bandwidth utilization of output port bandwidth capacity by monitoring the same and asserting backpressure toward the queue scheduler for any thread that is exceeding its bandwidth allocation. In another aspect, a switching fabric uses leaky buckets to apply backpressure in response to overutilization of downstream port capacity by particular subflows. In another aspect, a switching fabric includes a cascaded backpressure scheme.
