摘要
某型导弹测试设备控制总线为通用的ISA总线,而通信接口总线为非标准的MMИ总线。在此以FPGA为核心设计了一种ISA总线/MMИ总线转换电路,该电路可以完成2种制式的数据和控制指令转换。给出了转换电路原理框图、FPGA配置电路和地址比较电路原理图。实验结果表明该电路具有转换数据准确,工作可靠等优点。实际应用表明,该电路完全能达到测试设备的要求。
The control bus of a missile test equipment is the common ISA bus,but the communication interface bus is the non-standard ММИ bus.A FPGA-based data transform circuit was designed between ISA bus andММИ bus.This circuit can complete the format conversion of data and command between these two buses.The block diagram of the conversion circuits,the FPGA configuration circuit and the diagram of address comparison circuit are presented in this paper.Theexperiment results show that this circuit has the advantages of the high-accuracy data transform,reliable operation.The practical application proves that this circuit meets the requirements of testing equipments.
