摘要
文章介绍了一种在现场可编程门阵列(FPGA)上实现UART的方法。UART的波特率可设置调整,工作状态可读取。系统结构进行了模块化分解,使之适应自顶向下(Top-Down)的设计方法。核心部分采用有限状态机(FSM)实现,使控制逻辑直观简单,大幅度提高了设计效率。最后给出功能仿真结果,验证了整个设计的正确性和可靠性。
This paper introduces a method to implement UART based on Field Programmable Gate Array （FPGA）.Its baud rate can be set and the states can be read.The structure of this system is divided in modularization so that can fit the method TopDown.The hard core of this system is implemented with finite state machine （FSM）.It makes the logic of control more intuitionistic and more briefness.The efficiency of the design is improved in a wide range.Simulating experiments,present at last to proved the validity and reliability in the whole design.
