在MIL-STD-1553B总线和PCI总线的基础上,介绍一种基于CPCI总线的1553B板卡设计方法。硬件采用PLX公司的PCI9054芯片、DDC公司的BU-61580芯片和CPLD的构架,软件采用WDM模型的设备驱动程序访问板卡,并描述板卡的原理框图和软硬件的实现。测试结果表明:该总线数据传输可靠性高、稳定、无误码,效果良好,已在某机载军用产品设计上得到应用实现。 Based on the MIL-STD-1553B bus and the PCI bus, a 1553B board design method based on the CPCI bus is introduced. Hardware using PLX’s PCI9054 chip, DDC’s BU-61580 chip and CPLD architecture, the software uses the WDM model device driver to access the card, and describes the card’s block diagram and hardware and software implementation. The test results show that the bus data transmission has high reliability, stable, error-free and good effect and has been applied in the design of some airborne military products.
