摘　　要：本文给出了一种基于FPGA实现CPU接收多个UART串行接口数据的方式，实现了CPU与多个RS-232C传输标准外设的通信。文中给出了一些主要模块的Verilog HDL源程序，并进行了仿真。通过实验验证了其正确性、灵活性和可靠性，并得到实际应用。可以将该系统拓展运用到多种场合，具有较强的通用和推广价值。Based on FPGA, this paper presents a solution to the serial communication between CPU and muhi-UART. We describe the implementation of the communication between CPU and peripheral equipments abiding by protocol RS-232C. Some Verilog HDL source programs of the primary modules are given and used in the simulations. The validity, flexibility and reliability of the sys- tem are proved by test. The system can be used in various situations and has very strong generality and popularity.
