Procedures for Reed-Solomon Coding
http://web.eecs.utk.edu/~jplank/plank/gflib/ for an implementation of
Galois-Field arithmetic in GF(2^8) and GF(2^16), and for Reed-Solomon
coding as described in this paper.
In 1997, SPE published a tutorial by Plank
codes for erasure correction in redundant data storage systems. The
motivation of this tutorial was to present these codes, which are
typically described mathematically by coding theorists, in a way
accessible to the programmers who need to implement them.
The tutorial as published presented an information
dispersal matrix A, which does not have the properties claimed --
that the deletion of any m rows results in an invertable n*n
matrix. The purpose of this note is to present a correct
information dispersal matrix that has the desired properties, and
to put the work in current context.
