SKEW-CORRECTING APPARATUS USING ITERATIVE APPROACH

摘要

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.
