Design of Reed-Solomon Code in ADSL System with a TI C6201 DSP
Reed-Solomon (RS) codes play a major role in the Forward Error Correction (FEC) subsystem of Asymmetrical Digital Subscriber Line (ADSL) systems. It is a challenging task to implement RS codes of ADSL transceiver in software because of the high data throughput (1.5Mbps – 6Mbps). However, with the new generation of high-performance DSP from Texas Instrument (TMSC320C6201 capable of 1600MIPS) and careful design, we demonstrate that a software implementation of RS code in ADSL system is practical.
