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.
