Abstract
An intergrated circuit (IC) chip includes receiver circuitry to receive signals from a second IC chip. The receiver circuitry includes equalization circuitry having at least one tap to equalize the signals. The equalization circuitry includes a tap weight adapter circuit to generate at least one tap weight corresponding to the at least one tap based on edge information of previously received signals.
Claims20
An integrated circuit (IC) chip, comprising:
- receiver circuitry to receive signals from a second IC chip, the receiver circuitry including
- equalization circuitry having at least one tap to equalize the signals, the equalization circuitry including a tap weight adapter circuit to generate at least one tap weight corresponding to the at least one tap based on edge information of previously received signals.
An integrated circuit (IC) chip, comprising:
- circuitry to interface with a second IC chip via multiple links, the circuitry including multiple receivers, each receiver to receive signals via a corresponding link and comprising
- an equalizer having at least one tap to equalize the signals in accordance with at least one equalizer coefficient corresponding to the at least one tap;
- and
- a tap weight adapter circuit to generate the at least one equalizer coefficient from edge-based sampling information associated with prior received signals.
