Design and Simulation of UART Serial Communication Module Based on VHDL

Abstract

UART (Universal Asynchronous Receiver Transmitter) is a kind of serial communication protocol; mostly used for short-distance, low speed, low-cost data exchange between computer and peripherals. During the actual industrial production, sometimes we do not need the full functionality of UART, but simply integrate its core part. UART includes three kernel modules which are the baud rate generator, receiver and transmitter. The UART implemented with VHDL language can be integrated into the FPGA to achieve compact, stable and reliable data transmission. It's significant for the design of SOC. The simulation results with Quartus II are completely consistent with the UART protocol.
