Patent attributes
A method, apparatus, and computer-readable media for aligning n data signals received over a parallel bus, each of the n data signals comprising a training pattern, wherein n is at least two, comprises delaying each of the n data signals in accordance with a corresponding analog delay signal, thereby providing n corresponding delayed data signals; providing each of the corresponding analog delay signals based on the training pattern in the respective delayed data signal; delaying each of the delayed data signals by m bit times in accordance with a corresponding digital delay signal, thereby providing n corresponding aligned data signals, wherein m is greater than, or equal to, zero; and providing each of the corresponding digital delay signals based on the training pattern in the corresponding delayed data signal.
