No logic elements although I have an output

--- Quote Start ---

Without the code, I cannot tell. I assume your code is not what you already posted?

Storing an image in logic will be very expensive. You really should use ram.

I changed the code since as you advice me I can not fill same memory in two processes even if I am filling different locations. But I got the bigger problem of logic element localization. The new code is below , One process consumes 109 logic element!

Decompose array is an 8*8 array

LIBRARY ieee;

USE ieee.std_logic_1164.all;

Use ieee.numeric_std.all;

USE work.my_data_types.all; -- to define array of input ( package )

ENTITY NewD IS

PORT (

clk: in std_logic;

bufftest:out signed(9 DOWNTO 0));

end NewD;

Architecture behave of NewD is
