Design of TACAN video signal generate board based on PCI bus

针对某综合测试系统的测试需求,采用一种基于PCI总线的塔康(TACAN)视频信号产生电路设计方案,实现了塔康视频信号方位可调整的功能。介绍了系统的工作原理和设计要求;重点分析了硬件电路设计,采用PCI9054作为PCI接口器件,使用数字信号处理器TMS320VC5416作为运算中心、使用FPGA-EP2C8完成电路控制逻辑;同时分析了FPGA的程序开发、DSP程序设计及PCI板卡的驱动程序开发。结果表明,该方案适用于多种工控机平台,通用性强,具有良好的应用前景。

According to the testing demands of the integrative testing system,the solution of the TACAN video signal generate board based on PCI bus was adopted,and the function that the azimuth angle of the TACAN video signal was adjusted was implemented. The work principle of the whole system and the design requirements were introduced. The hardware design was analyzed in detail,including using the chip PCI9054 as the PCI bus interface,using the DSP-TMS320VC5416 as the data process unit,using the FPGA-EP2C8 to design the circuit control logic,and so on. The software design of FPGA and DSP were described,and the PCI driver was programmed. The solution could be used by many kinds of industrial control computer platforms,and it had strong universality and good application prospect.
