Abstract A real‐time high‐speed Reed‐Solomon coding—decoding system has been built based on a low‐cost signal processor TMS 32010. By taking advantage of the TMS 320 16‐bit multiplier and barrel shifter, the evaluation of the sum‐of‐products expression over a prime field can be simplified. Decoding of a (256,228) code with powerful error correcting capability over GF(257) has been implemented in this system, and the information bit rate is at least twice that of the ISDN B‐channel basic rate.
