Schifra is a very robust, highly optimized and extremely configurable Reed-Solomon Error Correcting Code library for both software and IP core based applications with implementations in C++ and VHDL. Schifra supports standard, shortened and punctured Reed-Solomon codes. It also has support for stacked product codes and interleaving.
Schifra provides a concise, predictable and deterministic interface which lends itself to easy and seamless integration into the development of complex data communication projects requiring Reed-Solomon error correcting code capabilities.
The Schifra C++ Reed-Solomon Error Correcting Code library has the following capabilities:
* Errors and Erasures
* Supported Symbol Sizes - 2 to 32 bits
* Variable Code Block Length
* User defined primitive polynomial and finite field
* Accurate and Validated Reed-Solomon Codecs - Complete combinatorial errors and erasures unit testing
