摘要 为有效解决现有ΓОСТ18977航空总线接口板接口少的问题,提出了一种采用主子板结构来设计实现USB、CPCI和PXI三种接口用途的总线接口板的方案。介绍了俄罗斯军用标准ΓОСТ18977,从系统硬件设计的角度出发,采用模块化设计方法设计了系统的硬件电路,分析了主板和各接口子板的功能,并对各接口子板进行了详细的设计,重点论述了基于双口RAM设计实现系统多接口用途的方法。经测试验证用本方法设计的接口板可以满足当前多种接口的需求。 To solve the problem that existing ГOCT18977 interface buses have few interfaces, a scheme of adopting main - board and sub - board to design the aero bus interface board is proposed, which can realize the multi- interface purpose of USB, CPCI and PXI. Russia military standard ГOCT18977 is introduced. In terms of hardware design, the modularization method is adopted to design the system circuit, the functions of main - board and each sub - board are analysed, and the sub - board interfaces are designed, with emphasis on the design and realization of multi - interface purpose of the system based on dual - port RAM. Test results show that the designed interface board can meet the need of many kinds of interfaces.
