通用串行总线的SD卡读写器的设计
用串行总线(Universal Serial Bus, USB)是连接外部设备的一个串口总线标准，在计算机上使用广泛，但也可以用在机顶盒和游戏机上，补充标准(On-The-Go)使其能够用于在便携设备之间直接交换数据。

基于FPGA的蓝牙HCIUART控制接口设计
通用异步收发器UART(Universal Asynchronous Receiver/Transmitter)是广泛使用的串行传输协议。串行外设用到异步串行接口一般采用专用集成电路实现。但是这类芯片一般包含许多辅助模块，而时常不需要使用完整的UART的功能和辅助功能，或者当在FPGA上设计时，需要将UART功能集成到FPGA内部而不能使用芯片。蓝牙主机控制器接口则是实现主机设备与蓝牙模块之间互操
