VLSI Reed-Solomon Encoder With InterleaverSize, weight, and susceptibility to burst errors reduced. Encoding system built on single very-large-scale integrated (VLSI) circuit chip produces (255,223) Reed-Solomon (RS) code with programmable interleaving up to depth of 5. (225,223) RS encoder includes new remainder-and-interleaver unit providing programmable interleaving of code words. Remainder-and-interleaver unit contains shift registers and modulo-2 adders. Signals on "turn" and "no-turn" lines control depth of interleaving. Based on E. R. Berlekamp's bit-serial multiplication algorithm for (225,223) RS encoder over Galois Field (2 to the 8th power).
