摘　　要：为了满足系统应用对1553B协议处理器的高传输率,高可靠性以及小型化提出的更高要求,在此采用有效集成CPCI总线接口协议芯片PCI9054和1553B总线接口协议芯片BU 61580的硬件连接方法,替代了采用传统的单片机作为控制芯片控制1553B总线的协议芯片BU 61580的方法。通过大量的测试,该板卡实现了基于CPCI总线进行1553B总线通信的目的。该板卡具备响应时间小,精度高的特点。该硬件组成电路包括:CPCI接口协议电路、FPGA时序和逻辑电路,1553B总线通信电路和秒脉冲电路。In order to meet the requirments of high bandwidth, high reliability and miniaturization of 1553B bus protocol processor, a hardware connecting method of effectively-integrated CPCI bus interface protocol chip PCI9054 and 1553B bus in- terface protocol chip BU-61580 is adopted in this paper, instead of the method, in which the traditional SCM is used as a con- trol chip to cor：trol the protocol chip BU-61580 of 1553B bus. The purpose of 1553B bus communication based on CPCI bus was realized with the board card that passed the test. The board card has the characteristics of short response time and high preci- sion. It includes CPCI interface protocol circuit, FPGA time sequence and logic circuit, 1553B Bus communicating circuit and second pulse circuit.
