Classification and control system for achieving client documents with an FPGA interfacing circuit

In this paper a classification and control system based on the use of personal computer is realized for people who want to achieve their documents in public utility offices. It is specially designed to bring about order, efficiency and comfort in different places. It consists of two parts, the first is software program designed in Visual Basic, Which will be used to classify people according to their demands. On entering the reception department of the office, a client will face a dedicated console. He selects a key relates to the process he wants to achieve. Then the program will arrange these data to be used later on calling clients. Till now there are many people who are not accustomed to deal with the new technology. So in this paper the problem is solved and the client will keep his priority. The second part is an interface logical circuit between the PC and the declaration display. This interface is based on an FPGA integrated circuit. The 7-segment displays are used in stead of cathode ray tube as they are clearer in displaying data as well as easier in driving any number of them.
