Design of the Eighteen Routes intellectual
Contest Responder Based on FPGA
Abstract:According to the request of the design specification graduating,this design of eighteen routes intellectual contest responder based on FPGA can simplify the system.By using the EDA software platform of Max+plus II,we designed an intellectual contest device of experiment to answer the question preemptively based on FPGA.And presented each module and idiographic circuit diagram. Giving the VHDL source program that based on FPGA.By editing,compiling and device programming,files of device programming in circuit configurable are down loaded to the device of EPF10K10LC84_3 of PCB experimental plate. It achieved the expectant requirements of design after actual circuit testing and verifying.This circuit can not only realize to lock with each other and itself, but also use the voice,arithmetic figure to hint the result at the same time.Reduce the lack of wrong answering because of responder late.It facts quick,having much more function and good using.
