摘要： Simplified RS (Reed-Solomon) code decoder that obviates error value polynomial calculation. A novel means is presented herein by which error magnitudes (or error values) can be calculated directly without requiring the generation of an error value polynomial (EVP). Modification of the Koetter decoding approach and the Forney formula are employed herein to perform the direct calculation of the error values. This approach is operable to save computation clock cycles that would normally be used to compute the EVP, and these clock cycles may be used to reduce the otherwise required parallelism and complexity in the ECC design that may be needed to perform the error correction in the allotted time and may also result in power savings. Some advantages related to this may approach include lower risk, less design time, and more scalability in an overall design.
