But in the parameters before the code you declare that the code polynomial is p(x) = x^3+x+1.

it is the generator polynomial for RS(7,3)

But what is the logic behind using 5,1,5,4 to create this constant array?

is simply a constant array
(5,1,5,4)
represented as std_logic_vector at C_M bits

I’d like to ask you how did you choose the G_poly :
constant G_GPOLY : t_pipe_enc := (
conv_std_logic_vector(5,C_M),
conv_std_logic_vector(1,C_M),
conv_std_logic_vector(5,C_M),
conv_std_logic_vector(4,C_M)); Please??
I can’t understand the structure of this conversion nor the values “5,1,5,4” that you picked to generate this poly
