Abstract
A method and associated processing module for an interconnection system, providing a pre-tap tuning directing and a post-tap tuning directing. The interconnection system includes a transmitter filter and a receiver equalizer; the transmitter filter performs filtering according to a pre-tap and a post-tap, and the receiver equalizer performs equalization according to an equalizer tap. The pre-tap tuning directing includes: forming an indicative pattern with a plurality of data samples and a transition sample from an equalized signal, comparing if the indicative pattern matches predetermined pattern(s), and accordingly directing whether the pre-tap is incremented/decremented. The post-tap tuning directing selects whether the post-tap is incremented/decremented according to a positive/negative sign of the equalizer tap.
