摘要： This algorithm and apparatus provides the ability to determine the amount of skew that should be injected into a high-speed data communications system consisting of a plurality of lanes comprising a data bus on a per lane basis, relative to a reference lane, for the purpose of compensating for inherent system skew. By knowing the relative amount of skew that each lane requires for alignment, an appropriate amount of skew can then be injected on each lane to provide alignment and thus compliancy with relevant standards, such as the Sxl-5 standard, in terms of data skew specifications. These relative skew amounts for each transmitting lane are determined using a methodology involving internal loopback and characteristics from the connected communications element to the chip receive path.

摘要： A method of performing forward error correction with configurable latency, where a configurable latency algorithm evaluates a target Bit Error Rate (BER) against an actual BER and adjusts the size of a configurable buffer such that the target BER may be achieved when utilizing the smallest buffer size possible. When errors are corrected without the utilization of each of the configurable buffer locations, the algorithm reduces the size of the buffer by y buffer locations; the algorithm may continue to successively reduce the size of said buffer until the minimum number of buffer locations are utilized to achieve the target BER. If the buffer locations have been reduced such that the buffer size is too small and the target BER cannot be achieved, the algorithm may increase the size of the buffer until the minimum number of buffer locations are utilized to achieve the target BER.

摘要： An apparatus for determining the amount of skew to be injected for system skew compensation in a high-speed data communications system including a plurality of lanes with a data bus per lane. Such skew compensation is necessary due to inherent system skew. By iterating through the possible intervals within the maximum expected skew search space, the correct combination of search space intervals for all lanes can be determined to provide alignment and thus compliancy with relevant standards, such as the SFI-5 and SxI-5 standards, in terms of data skew specifications.

摘要： In an arrangement of the disclosed systems, devices, and methods, a codeword encoded with a first number of check symbols is received and asymmetrically processed according to a second number of check symbols, where the second number of check symbols is less than the first number of check symbols, to produce an error locator polynomial and an error evaluator polynomial. A derivative of the error locator polynomial is produced by outputting a first polynomial term and a second polynomial term, wherein the second polynomial term is a constant. The derivative of the error locator polynomial is produced using a variable finite-field multiplier and without use of a divider.
