ntRSD Configurable Reed Solomon Decoder

From Noesis Technologies P.C.

Description

ntRSD core implements a time-domain Reed-Solomon decoding algorithm. The core is parameterized in terms of bits per symbol, maximum codeword length and maximum number of parity symbols. It also supports varying on the fly shortened codes. Therefore any desirable code-rate can be easily achieved rendering the decoder ideal for fully adaptive FEC applications. ntRSD core supports erasure decoding thus doubling its error correction capability. The core also supports continuous or burst decoding. The implementation is very low latency, high speed with a simple interface for easy integration in SoC applications.
