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.

The project 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.

Here are some key features of "Schifra":
