Architecture for VLSI design of Reed-Solomon encoders

A description is given of the logic structure of the universal VLSI symbol-slice Reed-Solomon (RS) encoder chip, from a group of which an RS encoder may be constructed through cascading and proper interconnection. As a design example, it is shown that an RS encoder presently requiring approximately 40 discrete CMOS ICs may be replaced by an RS encoder consisting of four identical, interconnected VLSI RS encoder chips, offering in addition to greater compactness both a lower power requirement and greater reliability.
