    Forward Error Correction (FEC) is a key component in communication system which mostly contains scrambler, Reed-Solomon coding, interleaving, and trellis coding. For the performance and complexity issues, design parameters are different in various applications. In this paper, a multi-mode FEC processor is presented to meet different system requirements with a power and area efficient architecture. The proposed processor is fully compliant to ITU-T J.83 cable modem system including the reconfigurable Reed-Solomon decoder and memory-based universal convolutional interleaver. With 0.18um 1P6M CMOS technology, the simulation result shows the FEC decoder can work over 100MHz while costs 54.5K gate counts and two 376×8 bits embedded duel-port SRAM. The average power consumption in most critical mode is about 34.2mW at 100MHz. While running at 7MHz that meets symbol rate of cable modem, the power dissipation is 2.32mW.
