I am using 12bit ADC (AD7476)and cyclone-1 FPGA. input analog value need 
to read in FPGA and display through RS232 .Kindly help me in VHDL 
coding.

Show what you have and describe the problems you encounter with that. 
Then maybe one is able to help you. But no one will do your 
job/homework for free.

A little hint: you may use a SPI master and connect it in a clever 
manner to a RS232 TX engine. Maybe in between you must scale the ADCs 
values and translate the  binary values to BCD or to ASCII...

To get an idea what to do have a look there (its German):

And to controll that all you will additionally need a FSM with a few 
states...
