基于奈奎斯特采样的FPGA异步串行通信接口设计
Design of FPGA Asynchronous Serial Communication Interface Based on Nyquist Sampling
摘要
Abstract
In asynchronous serial communication,due to the frequency limitations of serial interface hardware devices,as well as the effects of signal jitter and environmental interference caused by signal jumps,communication interface that it uses traditional methods for implementing asynchronous serial communication cannot reliably complete high-speed communication.It uses VHDL language to design an asynchronous serial communication interface based on Nyquist,which includes three modules:data reception,data transmission,and a sampling clock with a 2x baud rate.The joint simulation of ISE and ModelSim and practical engineering verification show that the interface designed using the new method can make system digital communicate with external devices stably and reliably at a high speed of 5 Mbit/s.关键词
