Abstract:
1. A method for an interconnection system, the interconnection system comprising a transmitter filter and a receiver equalizer, the transmitter filter arranged to filter a first signal based on a pre-tap and a post-tap, and accordingly provide a second signals; the receiver equalizer arranged to equalize the second signal based on an equalizer tap and accordingly provide a third signal, and the method comprising: performing, by a hardware processor a pattern comparison step for forming an indicative pattern according to a plurality of data samples of the third signal and a transition sample of the third signal, comparing if the indicative pattern matches a predetermined pattern, and accordingly providing a comparison result, wherein the transition sample is sampled between two of the plurality of data samples; and performing a pre-tap tuning directing step for, according to the comparison result, directing whether the pre-tap is incremented or decremented; and performing a post-tap tuning directing step for, according to a sign of the equalizer tap, directing whether the post-tap is incremented or decremented.
