基于BU-61580的1553B总线接口设计

Design of 1553B bus interface based on BU-61580

为提高1553B总线接口的实时性并简化接口逻辑,从总线接口的应用需求出发,设计了一种基于专用接口芯片和DSP控制器的1553B总线接口。该接口采用BU-61580作为协议引擎,采用TMS320F2812作为主处理器,只有少量的粘合逻辑,无需CPLD即可完成无缝衔接。该接口实时性好,可靠性高,硬件电路简单。以远程终端模式为例,对设计的1553B总线接口进行了测试验证。

An efficient design of 1553B bus interface is proposed based on protocol chip and DSP controller.The proposed design uses BU-61580 as the protocol chip and TMS320F2812 as host processora,nd interfaces them with minimal glue log-ic.Accordingly CPLD which was introduced as logic integration is not needed.This interface not only is real-time,highly reli-able,but also has compact hardware structures.It is tested and verified at remote terminal mode as an illustration in the end.
