ntRSC_IESS core is a highly integrated solution implementing a time-domain Reed-Solomon Forward Error Correction algorithm. The core supports several programming features including codeword size, error threshold, number of parity bytes, reverse or forward order of the output, mode of operation (encode, decode or pass-through), shortened code support, erasures or error only decoding. Very low latency, high speed, simple interfacing and programmability make this core ideal for many applications including Intelsat IESS-308, DTV, DBS, ADSL, Satellite Communications, High performance modems and networks.
