Abstract
Systems and methods are disclosed for data processing, and more particularly for equalizing a data signal during both real time (i.e., on the fly) and retry operation. The system may include a first equalizer circuit operable to equalize a first sample set, and a second equalizer circuit operable to equalize a second sample set. The system may include a third equalizer circuit operable to equalize a summed data set to yield a third equalized output. The system may include a summation circuit connected to the first equalizer circuit, the second equalizer circuit, and a switch circuit. The summation circuit is operable to sum at least the first equalized data set and the second equalized data set to yield the summed data set. The switch circuit selectively provides the third equalized data set to the summation circuit.
