摘　　要：通用异步收发器(Universal Asynchronous Receiver/Transmitter,UART)具有传输线少、可靠性高、波特率可调等优点,广泛应用于数据通信和控制系统。基于开放式多媒体应用平台(OMAP),采用FPGA的UART模块和MAX1500的SIM卡模块,将I/O线与SIM卡进行通信,实现了手机终端利用UART异步串口读写SIM卡数据的目的;在此过程中,由于实行奇偶检验,保证了传输数据的正确性和可靠性。Universal asynchronous receiver/transmitter （UART） has wide applications in data communication and control system. It features fewer transmission lines, high reliability and adjustable baud rate. Based on the OMAP platform and using UART module on FPGA and SIM card on MAX1500, communications were made between I/O interface and SIM card. Data in SIM card on mobile phones were accessed by using asynchronous serial port on UART. In this experiment, parity check was performed to ensure correct and reliable data transmission.
