摘　　要：针对飞行仿真转台系统的上下位机进行数据传送的任务,设计并调试了基于FIFO器件的16位并行输入输出接口通讯电路。该电路具有占用机器时闻少,传送数据量大,成本低并且运行可靠的特点,满足了系统实时控制和传送数据的要求。通过实际运行证明该16位并行输入输出接口通讯电路达到了设计指标,圆满完成了配合整个控制系统的任务。The design of data communication interface is introduced according to the task of communication between down-controller and up-computer of aviation simulator＇s control system, This circuit has the characteristics of taking little time and transmitting large amount of data, At the same time. this circuit meets the requirements of computer control and transmission. The experimental results prove that this 16 Bit parallel data communication interface attains the performance index and accomplishes the task of coordinating the whole control system.
