使用FPGA的FIFO，状态机，乒乓操作等实现了异步UART。,The use of FPGA-FIFO, state machine, ping-pong operation to achieve the asynchronous UART.

在FPGA外扩用FT2232 实现UART TO USB 2.0 的通信。-The FT2232H is a USB2.0 Hi-Speed USB Device to FIFO IC. This core allows the use of this chip with an FGPA design in high speed FT245 style synchronous FIFO mode. Data rates up to 25 mbytes/s can be achieve
