Using FPGA to Design a Wireless Order System for Noshery

In this paper, a method of design a kind of wireless order system is put forword, sepecially for noshery. Upper machine (the cashier desk) and lower machine (terminal equipment) are included in the system, those will be designed separately because of different function but the design of the terminal equipment is the emphasis. The system use FPGA as control and logic core to cooperate with many peripherals since FPGA has embedded soft core processor Nios II, which has the same powerful function as hardcore just like ARM or MIPS. nRF401 is used to transmit wireless data between two parts and it is connected by uart to processor. The system can reslove the problem of waiting in noshery during the peak period so save the time for the customer. And because of the reprogrammable characteristic of FPGA, it is easy to update for different noshery to be custom system.
