Matrix composed by two matrix

[lvcargnini]

Hi,
I have a matrix of (0 to 53, 0 to 67) and i create other two matrix
one of x(0 to 53, 0 to 53) and another y(0 to 53, 0 to 5) how could i
map this two matrix on bigger matrix ?
the easy way, correct way, the combinatorial way.
To do this outside an process statement or even inside a process.

Write a conversion function that takes the two smaller matrices
and returns a value of the large matrix type. Use FOR loops
inside this function to do the copying.

Hi,
all matrix are of type std_logic. So the manner that you are saying me
to do is using forr loops inisde a process or a function, correct ?
but if a create a function, I don't need to call the function inside a
process block ?

Yes; but why is that an issue? EVERY piece of procedural code in
VHDL runs inside a process, although sometimes the process is
disguised (for example, a concurrent signal assignment is in
fact a process). So you could easily write a concurrent
signal assignment that calls your function:

big_matrix <= combine_function (small_matrix, tiny_matrix);

That's why functions are such a neat solution for this sort of
thing - you can use them all over the place.
