单片微型计算机简称单片机，它是将中央处理器（CPU）、存储器（RAM,ROM）、定时/计数器和各种接口电路都集成到一块集成电路芯片上的微型计算机。随着计算机技术尤其是单片机技术的发展，人们已越来越多地采用单片机来对一些工业控制系统中如温度、湿度等参数进行检测和控制。PC机具有强大的监控和管理功能，而单片机则具有快速及灵活的控制特点，通过PC机的RS 232串行接口与外部设备进行通信，是许多测控系统中常用的一种通信解决方案。因此如何实现PC机与单片机之间的通信具有非常重要的现实意义。针对一些远距离控制或者是危险性比较高的数据采集和控制的应用情况，本文主要介绍一种用双工方式实现PC机与单片机之间的

基于USB 总线的PC 机与FPGA 通信系统，采用IFCLK 输出内部时钟源的时钟信号，FLAGA-FLAGD
用于报告不同FIFO 状态。由FPGA 判断引脚电平高低决定何时向FIFO 读写数据。SLOE 作为输出使能，控制FIFO
数据端的输出控制。SLRD 是FIFO 读取数据控制端，在异步方式下，由FPGA 输出高低电平控制数据的读取。
