  • System for an adaptive floating tap decision feedback equalizer
    Patent number: 8121183
    Abstract: A method for adaptive selection of floating taps in a decision feedback equalizer including the steps of (A) determining values for a predefined metric for tap positions within a range covered by a decision feedback equalizer (DFE) and (B) setting one or more floating taps of the DFE to tap positions based upon the values of the predefined metric.
    Type: Grant
    Filed: July 13, 2007
    Date of Patent: February 21, 2012
    Assignee: LSI Corporation
    Inventors: Lizhi Zhong, Ye Liu, Catherine Yuk-fun Chow, Ryan Jungsuk Park, Freeman V. Zhong, Amaresh V. Malipatil
  • System for automatic bandwidth control of equalizer adaptation loops
    Patent number: 7813415
    Abstract: A method to reduce peak power consumption during adaptation for an integrated circuit (IC) with multiple serial link transceivers including the steps of (A) inactivating equalizer adaptation loops until a triggering event occurs, (B) when the triggering event occurs, determining whether the triggering event is a minor change or a major change, (C) when the triggering event is a minor change, spreading out activation of adaptation loops in time, and (D) when the triggering event is a major change, simultaneously activating all adaptation loops.
