摘要
设计了一种基于FPGA的1553B总线控制系统,用于RS-422接口和1553B总线接口之间的数字量转换和传输。文中详细阐述了该系统的硬件电路,BC模式配置和FPGA控制逻辑的设计方法,来说明系统功能的实现过程。采用FPGA作为主控制器,对1553B接口芯片进行了配置,给出了程序设计流程和控制时序。测试结果表明,该系统完全满足实际工程需要,具有很高的可靠性,并且已成功运用于某工程应用项目中。
A 1553B Bus Control System Based on FPGA was designed,by the RS-422 interface and 1553B bus interface between digital conversion and transmission. Elaborated hardware circuit of the system,the BC mode configuration and the method of FPGA control logic to illustrate the process of the realization of the system function. FPGA as the master controller,configurated the 1553B interface chip,provided program design process and control the tim- ing. The test results show that the system fully meet the needs of practical engineering,has a high reliability,and has been successfully applied to a bus controller project.
