FUNCTIONAL DESCRIPTION

CORE: Core module interconnects all the sub-modules in the FEC_RS (73,69) IP. Ports of core module are the top level ports for the FEC_RS (73,69) IP.

ENCODER: Encoder module is used to encode the input data and calculate the parity.

GALIOS MULTIPLIERS: It is used in encoder to calculate parity symbols using galios multiplication and input data and in decoder to compute syndromes and error values.

STATE REGISTERS: State registers are used in encoder to store intermediate parity states while processing the data symbols sequentially.

CONTROLLER: It resets the encoder state registers at right time so each codeword is encoded correctly without mixing data from different frames.

DECODER: Decoder module is used to detect and correct the errors with the help of syndrome calculation.

BIT LOCKER: Bit Locker is used to lock the correct codeword.

SYNDROME CALCULATOR: Syndrome Calculator is used to detect the error.

KEY SOLVER: Key solver is used to solve key equation, which determines the error-locator and error-evaluator polynomials.

ERROR CORRECTION: Error correction is used to correct the error.
