参考黑金的串口收发,将串口收发和fifo写在一个.v文件中,操作接口主要变为fifo,rx_fifo_empty!=1时,有收到数据,读出来即可,发送串口只需要往fifo中存入数据。接收时判断起始位为低和停止位为高,防止上电前串口上一直有数据发送进来而引起的误码。点赞(0) 踩踩(0) 反馈 ...

基于FPGA实现uart串口模块(Verilog)---接收模块及思路总结 uart通信协议简单理解为串转并和并转串的两个模块。同时必须保证数据的正确性。且输入输出端为串行。 此次实现uart协议通过回环来保证数据接收发送的正确。用状态机来理解(也不知道是不是状态机,觉得这样写比较好理解)。 两个接收,发送是对于开发板来说的...
FIFO、UART、ALE解释 FIFO存储器 FIFO是英文First In First Out 的缩写,是一种先进先出的数据缓存器。 它与普通存储器的区别是没有外部读写地址线,这样使用起来非常简单,但缺点就是只能顺序写入数据,顺序的读出数据,其数据地址由内部读写指针自动加1完成,不能像普通存储器那样可以由地址线决定读取或写入某个指定...
When using interrupts, it doesn't generate them in a way that takes advantage of the fifo's. We had to modify our verilog code so that interrupts were generated only when the fifo was 75% full for example. This was done by changing the "qualified_irq" assignment. Unt...
In this paper, we present the design of UART modules based on Verilog HDL. The design consists of the transmitter, receiver, baud rate generator and asynchronous FIFO (First in First Out) buffer. The design is synthesized in Verilog HDL and reliability of the Verilog HDL implementation of ...
Code in both VHDL and Verilog for FPGA Implementation Do you know how a UART works? If not, first brush up on thebasics of UARTsbefore continuing on. Have you considered how you might sample data with an FPGA? Think about data coming into your FPGA. Data can arrive by itself or it ca...

Hi. i have one design that is UART written in verilog code. The simulation is successfully done. However, when i program my design to the DE2 board and connect it to the PC using the RS232, there is no output shown in hyper terminal. i would like to ask a favor that help me to...
(原创)system verilog——uart发送模块的设计 仿真结果如下: p_start是验证从载入要发送的数据到发送低有效的起始位这段时间的时序是否正确,,p_shift是验证从准备好开始发送到发送过程中 的数据的九次移位是否正确,p_state是跟踪发送过程中状态机的状态。 具体代码如下: Code 1`timescale 1ns/10ps 2module ...
