how to get the value of GFILog (FF)
Hi,
I need to implement Galois Field division in my application.
Please follow the link for the reference
http://www.xilinx.com/support/docume...es/xapp865.pdf.
In this document GFILog (FF) and GFLog(00) is not defined.
Please suggest me how can I calculate the value of these?
Thanks
Madan
Re: how to get the value of GFILog (FF)
it looks like we are in GF16 (judging from the fact that the LUT's are 15x15), so the field in question is:
![\frac{\mathbb{Z}_2[x]}{(x^8 + x^4 + x^3 + x^2 + 1)}](http://latex.codecogs.com/png.latex?\frac{\mathbb{Z}_2[x]}{(x^8 + x^4 + x^3 + x^2 + 1)})
i think you might find a more detailed answer here:
