摘要
提出了基于SmartFusion的UART的设计,阐述了通用异步收发器UART的功能特点,使用了硬件描述语言Verilog对各个模块进行了介绍,并给出了仿真结果。将UART核心功能放到FPGA中可以大大提高SmartFusion内Cortex-M3的执行效率,整个UART接口电路结构简单、升级方便、稳定性高,可以将其灵活地应用到各个通信系统中。
The design of UART based on SmartFusion is proposed, the universal asynchronous occurrence device functions and features of UART are expounded, using hardware description language Verilog to introduce each module , and the simulation results are given. Put the UART core functionality in FPGA can greatly improve the efficiency of SmartFusion Cortex-M3, the UART interface circuit has the advantages of simple structure, easy upgrade, high stability, can be flexibly applied to various communication systems.
