If you have the command order and a timing diagram for the bus, it should be fairly straight forward. You just write some controller for the chip and away you go. If you dont know where to start, I suggest a book on digital logic design and a VHDL tutorial.

i am designing an intelligent traffic light controllor which gives priority to emergency vehicles . i know vhdl and i am familiar with it all i cant understand is the gsm interface with fpga. what i want to do is the vehicle will send a message to gsm and the corresponding traffic light will trun gren and road will be cleard
