ABSTRACT:
Apparatus for encoding and decoding the Alternant code family including three parallel special purpose Galois Field processors, and a timing and control unit. The special purpose processors jointly process a time domain algorithm relatively independently of the timing and control unit, and are adapted so that each step of the time domain algorithm is handled by one or more of the processors.
