  • Method and apparatus for performing non-unique data pattern detection and alignment in a receiver implemented on a field programmable gate array
    Patent number: 11190335
    Abstract: A method for performing pattern detection and alignment on a programmable logic device is disclosed. A word aligner unit, implemented by a hard intellectual property block, is configured to detect a plurality of control characters by recognizing a proper subset of bits that are common among the plurality of control characters. It is determined whether a predetermined number of consecutive control characters has been detected in a frame of data. A boundary location associated with a detected predetermined number of consecutive control characters from the word aligner unit is identified. The frame of data is aligned in response to the boundary location associated with the detected predetermined number of consecutive control characters.

  • Techniques For Word Alignment Based On Transition Density
    Publication number: 20190280850
    Abstract: A receiver circuit includes a transition density detector circuit that generates a transition density signal based on a comparison between a transition density of data words to a transition density threshold. The receiver circuit also includes a bit shift and pattern detector circuit that bit shifts one of the data words to generate bit shifted data in response to the transition density signal indicating that the transition density of the data words has reached the transition density threshold. The bit shift and pattern detector circuit counts a number of bits shifts performed on the bit shifted data to locate a synchronization character. The receiver circuit also includes a word alignment circuit that bit shifts the data words by the number of bits shifts to generate word aligned data.
