Overview

SmartDV’s RS-FEC (198,194) IP is a silicon-proven, high-performance Reed-Solomon Forward Error Correction solution purpose-built for SoC designs requiring reliable, hardware-accelerated error correction across high-speed serial interfaces, display subsystems, storage controllers, and wireless applications. Implementing the RS(198,194) algorithm over GF(2⁸) with 8-bit symbols and 32-bit parity generation, it delivers robust symbol error correction through a fully pipelined architecture optimized for the low-latency, high-throughput demands of modern high-speed SoC designs.

As data rates continue to climb across every class of high-speed serial interface, reliable forward error correction has become an essential building block for any SoC targeting aggressive BER requirements. SmartDV’s RS-FEC (198,194) IP gives SoC teams a production-tested, algorithmically complete FEC implementation covering the full pipeline from parity generation through syndrome calculation, Berlekamp’s algorithm, Chien search, and pipelined error correction, that can be integrated independently of any specific protocol or interface standard wherever Reed-Solomon FEC is required.

Built for design flexibility and silicon efficiency, the IP core is highly configurable for both ASIC and FPGA implementations, with a strong focus on area optimization, power management, and peak performance. Its pipelined architecture, bit locker mechanism, and clean host interface enable fast integration and confident design bring-up across a wide range of advanced process nodes and target applications.
