Anti-radiation RS code decoding circuit

The invention discloses an anti-radiation RS code decoding circuit. The circuit comprises: an adjoint calculation module used for calculating the received code word R(x) to obtain an adjoint polynomial S(x); a key equation solving module used for carrying out key equation solving on the adjoint polynomial S(x) to obtain an error position polynomial [lambda](x) and an error value polynomial [omega](x); an error pattern searching module used for calculating to obtain an error position and an error value corresponding to the error position; a data caching module used for caching the received codeword R(x); and an error correction output module used for reading the code word R(x) cached in the data caching module, performing error correction on the read cached code word R(x) according to theerror position calculated by the error pattern search module and the error value corresponding to the error position, and outputting a code word C. According to the anti-radiation RS code decoding circuit, the area of the circ
