Need help - Transmitter UART schematic block diagram

Hello world

I need help to make a transmetter UART in schematic block with Quartus II.
the system schema (full)


Serial_Transmitter VHDL code

I can only use gates, flip-flops, registers, counters, and others combinational or sequential circuits.

Thanks in advance.

someone can interpret me the VHDL code ?

Depends on what kind of help you need. I could look over any code you have and offer suggestions.
