Abstract: According to the features of Universal Asynchronous Receiver Transmitter(UART), a FPGA-based embedded design algorithm is proposed. The algorithm includes state machine design and level design techniques. The transmission function of full-duplex to receive/sends data is realized. The functional test circuit of UART is also designed. Experimental results show that the design has the advantages of programmable digit of the send/receive data and functional expansion etc.

Key words: universal asynchronous receiver transmitter, FPGA, finite state machine
