摘要
提出了一种利用异步串行通信接口电路的FPGA实现方法,该方法运用双端口RAM乒乓操作、CRC校验、状态机、组帧等操作描述了各个功能模块的FPGA设计,同时给出了该异步接口电路在集成开发软件Xilinx ISE11.1下的Modelsim仿真结果。结果证明,该异步串口通信设计可以简化电路并提高程序的灵活性和实用性,有利于程序在不同场合下的应用。
FPGA implementation method of using asynchronous serial communication interface circuit is proposed.The dual-port RAM pingpong operation,CRC check,state machine,framing and other operations are used in the method to describe,the FPGA design of each module.The Modelsim simulation results of the asynchronous interface circuit under the integrated development of software is presented.The results show that the asynchronous serial communication with FPGA resources can simplify circuit design,improve program flexibility and practicality,and benefit program application in different occasions.
