hello,

I'm currently working on a component that has the following behavior:

1) control component:

ENTITY CONTROL IS

GENERIC (FILE_NUMBER: NATURAL: = 10);

PORT (FINISHED: IN STD_LOGIC_VECTOR ((FILE_NUMBER - 1) downto 0);
CLK: IN std_logic;
RST: IN std_logic;
ENABLE: OUT STD_LOGIC_VECTOR ((FILE_NUMBER - 1) downto 0));

END CONTROL;

1.1 - Has the function of signaling which file must be read. It 
indicates that through a bit of door ENABLE.
1.2 - when the file finished being read, it indicates through a bit of 
door FINISHED.
1.3 - The control then passes to another file and repeat 1 and 2 until 
no more files to be read.
-------------------------

2) component of the reading of files

ENTITY IS ARQ_MOD

GENERIC (DATA_SIZE: NATURAL: = 16);

PORT (ENABLE: IN std_logic;
FINISHED: OUT std_logic;
OUTPUT_DATA: OUT STD_LOGIC_VECTOR ((DATA_SIZE - 1) downto 0));
ARQ_MOD END;

1.1 - Has the function to open a file when the door ENABLE = '1 '.
1.2 - Read the file until the end.
1.3 - FINISHED = '1 '. indicates that the file over.
1.4 - OUTPUT_DATA = 'Z'. because the modules file are all connected to a 
bus.
--------------------------------

need help on the following issues:

* A plan to use a control unit and connect a number N of modules file to 
this control unit, for example using a LOOP GENERATE. the output of them 
was connected to a single bus. When ENABLE = '0 '-> OUTPUT_DATA =' Z ', 
then only the module in use has possession of the bus.
* I would like to know how to pass the path of the file to file_open 
dynamically.
* also, i need some ideas of implementation....


here is the idea of ​​the circuit.
