Patent ID: 8199804

Claim:
A method of configuring equalization circuitry, said method comprising: receiving a first set of feedforward taps with a plurality of data inputs of a multiplexer, wherein respective ones of feedforward taps are coupled to respective ones of the plurality of data inputs, and wherein an output of the multiplexer is coupled to feedforward filter circuitry; receiving a first set of feedback taps of feedback filter circuitry; coupling one of the plurality of data inputs of the multiplexer to the output of the multiplexer, based on a control signal received at a control input of the multiplexer, to filter an input signal with the feedforward filter circuitry, wherein the coupling generates a second set of feedforward taps; and adding, in response to the coupling, a compensating set of feedback taps to said first set of feedback taps to generate a second set of feedback taps in communication with said feedforward filter circuitry to filter said input signal.
