This paper proposes the systolic decoder for Reed-Solomon (RS) codes based on systolic algorithms. Three steps of decoding procedures for RS codes can be reduced to simple repetitive algorithms and thus can be realized by one-dimensional systolic arrays, each operated by simple controls. The decoding system is a cascade connection of these cell arrays in one dimension. In this paper we also design three types of cells building arrays for RS codes on GF(28). Each cell has a size that permits its integration in a one-chip LSI and we can determine the number of cells according to the error correcting ability for codes. [ABSTRACT FROM AUTHOR]
