摘要
为实现基带信号的高速异步串行传输,本文用VHDL语言设计了一种以RS485物理层标准为基础,对数据帧位检测来实现信号接收的方法。通过计算机仿真和实验测试,在复杂可编程逻辑器件(CPLD)平台上实现了数据异步传输。证明本文给出的设计可以实现数据的高速可靠传输。
In order to realize the asynchronous serial transmission of basedband signals, this paper uses VHDL language to design a kind of RS485 physical layer standard based on data frame detection to achieve data reception.Through computer simulation and experimental testing, asynchronous communication is realized on the Complex Programmable Logic Device(CPLD) platform.The design given in this paper can achieve high-speed and reliable transmission of data.
