Realization of UART Communication Based on FPGA

This paper introduces a method to implement UART based on Field Programmable Gate Array( FPGA) . At first a theory on asynchronous serial communication UART is provided ,and then hardware interface circuit design ,coding with Verilog to realization of communication based of FPGA are described. The structure of this system is divided in modularization so that can fit the method Top-Down. Simulating experiments present at last to proved the validity and reliability in the whole design.
