this algorithm and apparatus provides the ability to deskew a plurality of lanes comprising a data bus in a high - speed data communications system . this deskewing 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 sxi - 5 standard , in terms of data skew specifications .
