Hello Experts,

In one of my application I need to implement GALOIS FIELD arithmetic (used in Reed Solomon algorithm) for division and multiplication.
As referenced to the link "http://www.xilinx.com/support/documentation/application_notes/xapp865.pdf". In GFilog and GFLog table GFilog(FF) and GFLog(00) values are not defined.
How can we get the values of GFiLog(FF) and GFLog(00)?

They don't have values. They are undefined (similar to 1/0). You just handle these cases separately however works best for your application.
