UART自适应波特率发生器的设计与仿真
Design and Simulation of UART Adaptive Baud Rate Generator
摘要
Abstract
To improve the communication baud rate between various microprocessors and embedded systems,this paper improves the traditional baud rate adaptive detection technology and designs a UART module based on FPGA and Verilog HDL hardware description language that can flexibly and efficiently configure baud rate parameters.Firstly,the traditional technique of detecting baud rate by sending fixed data is improved,and an adaptive baud rate generator is designed using feature value matching method combined with table lookup comparison method to achieve automatic and efficient detection of baud rate and complete corresponding parameter configuration.Then use Modelsim to perform system level simulations on the functions of each module.The simulation results show that the baud rate generator can automatically establish a serial communication link,ensure stable and reliable data transmission,improve detection efficiency,and reduce system resource overhead.关键词
