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 ...
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...
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...

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...

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...
