The proposed work in this paper describes the implementation of universal asynchronous transmitter and receiver, that is UART. The UART is a type of a serial communication protocol which serves the purpose of full duplex communication over a serial link. The UART here in is described by hardware description language that is Verilog HDL. The Verilog HDL code has been simulated in the ModelSim 10.1d and implemented on Altera DE1 board. © 2015 IEEE.
