Embodiment Construction
[0080] The following will clearly and completely describe the technical solution in this embodiment with reference to the drawings in this embodiment. Obviously, the described embodiment is only a part of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0081] In order to solve the problem in the prior art that the traditional decision feedback sequence predictor (DFSE) cannot run in the FPGA because of its too long critical path, and the overall performance of the 1000BASE-T physical layer chip cannot be fully verified by the FPGA. Chip design brings huge risks and hidden dangers, and the invention provides a novel decision feedback sequence predictor.
[0082] The DFSE provided in this embodiment includes an intersymbol crosstalk shaping filter ISF, an...
