Hello I am having trouble understanding the algorithm implementation in hardware of the reduction process over galois fields of
In the following process it looks like we are calculating the zc(z) value from
2m-2 downto m
which the first half of c(z)
but I am not getting to understand what is r(z) and how it is obtained ?
r(z) shouldn't be fixed as
Z^m and if it s a polynomial what is its value and what is W?
and how is the process of z^k * r(z) viewed as in hardware
is it only left shift by 1 for each k and an and gate with r(z)?
