时统在作战系统中对各设备之间通信时间的统一同步起着重要的作用.本文主要介绍时统的研制过程以及CPCI板卡和FPGA的应用[1].板卡主要采用PCI9030作为CPCI接口电路的主要芯片.利用FPGA的可在线编程优点,可根据用户的需求修改参数,接收或产生不同频率、脉宽的时统信号,来满足不同系统对时统信号的要求,并且开发其在Windows XP和VxWorks操作系统下的驱动程序.%Timing in the combat system of the equipment of communication between the unity of the plays an inportant role,this paper mainly introduces the development process as well as to when the CPCI borad and the application of FPGA to do a simple introduction. The board users PCI9030 as the CPCI bus interface circuit of the main chip, using FPGA on-line programming advantages, according to the needs of users to modify the parameters, receive or produce different frequency, pulse width timing signal, to meet the needs of different systems on the signal requirements, and debeloped in the Windows XP and VxWorks operation system driver.
