Overview

RS codes are block codes especially used for forward error correction purposes. Reed-Solomon (RS) decoders are key components in digital communication systems such as Storage devices, Disk Drives, Digital video Camera, Wireless broadband systems, Wireless modems, Satellite communication and Broadcast equipments.

SeaSolve’s RS encoder/decoder delivers a technology independent high performance VHDL core that can be implemented on various standards such as DVB, ATM and Wireless.

The code uses a single clock for synchronous purposes. The code flags the failures and counts the number of errors corrected and possesses 64 bits error correcting capability. The number of errors corrected, symbol size and codeword length are programmable. The code also supports continuous input data stream with out gap between code blocks.

SeaSolve’s RS encoder/decoder combined with SeaSolve’s Viterbi Decoder will deliver a high performance error correcting system.
