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 uart_t...什么...

对于的ADC接口,则与选择的具体器件有关。可能还需要显示一下频率数值,这个就和 BCD(Binary-Coded Decimal,BCD)译码器及其接口,乃至液晶显示( Liquid Crystal Display, LCD)接口有关联了。这部分很重要,但是不是本讲的重点,且容贫道一嘴带过。 累加器部分,更加简单的,就是一个允许设置累加步长的累加器了。
