A VLSI design of a pipeline Reed-Solomon decoder.
A pipeline structure of a transform decoder similar to a systolic array is developed to decode Reed-Solomon (RS) codes.  An important ingredient of this design is a modified Euclidean algorithm for computing the error-locator polynomial.  The computation of inverse field elements is completely avoided in this modification of Euclid's algorithm.  The new coder is regular and simple, and naturally suitable for VLSI implementation.  An example illustrating both the pipeline and systolic array aspects of this decoder structure is given for a RS code.
