摘要： Various structures and methods are disclosed related to configurable scrambling circuitry. Embodiments can be configured to support one of a plurality of protocols. Some embodiments relate to a configurable multilane scrambler that can be adapted either to combine scrambling circuits across a plurality of lanes or to provide independent lane-based scramblers. Some embodiments are configurable to select a scrambler type. Some embodiments are configurable to adapt to one of a plurality of protocol-specific scrambling polynomials. Some embodiments relate to selecting between least significant bit (“LSB”) and most significant bit (“MSB”) ordering of data. In some embodiments, scrambler circuits in each lane are adapted to handle data that is more than one bit wide.

摘要： Systems and methods are disclosed for buffering data using a multi-function, multi-protocol first-in-first-out (FIFO) circuit. For example, a data buffering apparatus is provided that includes a mode selection input and a FIFO circuit that is operative to buffer a data signal between a FIFO circuit input and a FIFO circuit output, wherein the FIFO circuit is configured in an operating mode responsive to the mode selection signal.

摘要： In accordance with an embodiment of the invention, precision control of error injection may be accomplished by way of synchronous error signals accompanying data transfers along various pipeline stages of a data path. The synchronous error signals may be used to trigger error events in a given protocol logic block (i.e. in a given sub-component of the data path). The protocol logic block is configurable to determine whether any action is to be taken upon the assertion of the error signal. Multiple error events may be triggered as the data signal (and its accompanying synchronous error signal) passes through pipelined functions of the data path so as to create complex error conditions. In addition, deterministic handling of created errors may be accomplished using a loopback path with bypassable blocks on both forward and reverse transformations. Other embodiments, aspects and features are also disclosed.

摘要： Circuitry for detecting excessive runs of similar bits of data in a data stream is provided. The data stream is typically received as serial data operating in a serial clock domain. Run-length detection circuitry checks the received data for run-length violations while operating in a slower parallel clock domain, as opposed to the faster serial clock domain. An advantage of operating run-length detection circuitry in the parallel domain is that longer length run-length violations can be searched for in the received data, as compared to run-length detectors that operate in the serial domain. Another advantage offered by the circuitry is that the run-length violation signal can be provided to utilization circuitry asynchronously. This enables utilization circuitry to quickly capture the signal despite differences in clock domains (i.e., the clock domain of the detection circuitry and the clock domain of the utilization circuitry).
